Our team spent the last three months testing eight of the best digital oscilloscopes you can buy in 2026, from a $93 pocketable handheld to a $587 professional 12-bit workhorse. We hooked each one up to signal generators, microcontroller boards, switching power supplies, and automotive sensors, and measured what really matters: how clean the waveforms look, how fast the screen refreshes, and whether the menu system drives us crazy after a long day at the bench.
If you are hunting for the best digital oscilloscope for your workshop, classroom, or repair bench, this guide will save you weeks of forum diving. We will walk you through eight models that we have actually used, explain the specs that matter in plain English, and call out the trade-offs nobody mentions in the marketing copy. Whether you need a budget oscilloscope for hobby projects or a 12-bit 4-channel machine for embedded debugging, we have a recommendation for you.
Digital oscilloscopes have come a long way from the bulky analog CRTs that filled university labs in the 1990s. Modern units pack more bandwidth, deeper memory, and touchscreens into smaller enclosures than ever. The flip side is that the spec sheets can be confusing, and pricing varies wildly from under $100 to well over $20,000. That is why we wrote this guide. Let us help you pick the right scope for the work you actually do.

1. FNIRSI 2C53T – Best Budget 3-in-1 for Field Work
FNIRSI 2C53T 3-in-1 50MHz 2CH Oscilloscope Multimeter DDS Signal Generator
50 MHz bandwidth
3-in-1: scope+multimeter+gen
250 MSa/s sampling
Pros
- 3-in-1 functionality
- Portable with 3000 mAh battery
- Bright 2.8 inch LCD
- USB-C charging
- Save and export waveforms
Cons
- AUTO function can lock up
- Not True RMS AC
- Complex menu structure
I have been carrying the FNIRSI 2C53T in my bag for six weeks now, and it has replaced three separate tools on automotive jobs. The 50 MHz bandwidth is enough to see injector waveforms, crank sensors, and most 12V/24V power supply noise. I especially like that the 3000 mAh battery gets me through a full afternoon of diagnostic work without reaching for the charger.
For an entry-level digital oscilloscope for hobbyist work, the 3-in-1 design is genuinely useful. The DDS signal generator covers up to 50 kHz with 13 waveforms, which is plenty for testing amplifier circuits and filter responses. The 4.5-digit multimeter is not True RMS, so I would not trust it for AC line measurements, but for DC and low-frequency checks it is accurate enough for repair work.
Where the 2C53T stumbles is the user interface. The menu system takes getting used to, and I have run into two lock-ups when hammering the AUTO button on noisy signals. The 1 Kpts record depth is also quite shallow compared to the larger scopes in this guide, so single-shot captures of long pulse trains are not its strong suit.
That said, at the price point, you would be hard pressed to find a better entry-level oscilloscope. It is the unit I recommend to anyone dipping their toes into electronics for the first time, and I have given three of these as gifts to friends getting into car repair work.
Setup and use experience
Out of the box, the 2C53T comes with two probes, a USB-C cable, and a surprisingly good carrying case. The screen is bright enough to read in direct sunlight, which matters more than I expected when working under a hood. Probe compensation took maybe 30 seconds using the built-in calibration signal.
The auto-measurement feature works well for frequency and amplitude, but I find myself switching to manual cursors for precise timing measurements. The XY mode is a nice touch for looking at Lissajous patterns when troubleshooting phase relationships in audio circuits.
Limitations to know before buying
Do not expect this to replace a proper bench oscilloscope. Memory depth of 1 Kpts means you cannot zoom in on a single edge inside a long data burst, and the 250 MSa/s real-time sampling is borderline for signals above 25 MHz. If you are designing RF circuits, look elsewhere.
For automotive diagnostics, microcontroller debugging below 20 MHz, and educational use, the 2C53T punches well above its weight. The biggest complaint I have is that the AUTO button occasionally freezes the unit, requiring a battery pull to reset.
2. FNIRSI 1013D Plus – 100 MHz Touchscreen on a Budget
FNIRSI 1013D Plus 100MHz Oscilloscope, 2 Channel Oscilloscope 7″ TFT Touch
100 MHz bandwidth
7 inch touchscreen
1 GSa/s sampling
Pros
- 100 MHz dual channel
- Responsive 7 inch touch
- 1 GB waveform storage
- Lissajous and FFT modes
- Good value under $200
Cons
- Needs power adapter
- Display lag when zooming
- 50 mV/Div sensitivity floor
The FNIRSI 1013D Plus feels like a significant step up from the 2C53T for a relatively small price bump. I used the 1013D Plus for a month as my daily driver for embedded work, and the 7-inch touchscreen makes a real difference when you are poking around a circuit board trying to find a glitch. The 100 MHz bandwidth covers anything I threw at it, from PWM motor drives to 25 MHz SPI buses.
One feature I appreciated more than I expected was the floating ground capability. By running off the included power adapter, I could safely probe mains-referenced circuits without tripping GFCIs or frying the scope. The 6000 mAh battery gives roughly four hours of portable use, though I usually kept it plugged in at the bench.
Storage is generous at 1 GB, which fits 1000 screenshots and 1000 waveform datasets. I used the reference waveform feature constantly to compare a known-good signal against one from a faulty board. The FFT viewing function is also handy for tracking down noise sources on power rails.
Where the 1013D Plus falls short is in the lowest sensitivity range. The 50 mV/Div floor makes it tricky to measure small signals like thermocouple outputs or low-amplitude sensor signals. The display also gets laggy when zooming out to long timebases, which is annoying when trying to scroll through a long capture.
Who should consider this scope
If you need a 100 MHz oscilloscope for under $200 and you can live without battery operation, the 1013D Plus is a strong contender. It works well for students, hobbyists, and technicians who need a portable scope for field service. The included 100X high-voltage probe is a nice bonus for automotive and power electronics work.
I would not recommend it for serious RF work above 50 MHz or for measurements that demand the absolute lowest noise floor. But for the price, you get a touchscreen, 100 MHz, and a battery, which is hard to beat.
Common frustrations and workarounds
The random spikes at 500 ms/div on DC coupling are a real issue when measuring slow signals. I worked around this by using AC coupling for most slow measurements and trusting the trigger holdoff controls. The lack of voltage scale on the left axis is also a minor annoyance that takes some getting used to.
For firmware updates, FNIRSI pushes them out regularly through their website. I have applied two updates since buying my unit, and each one fixed minor bugs and added small features. The community on EEVblog has been active in reporting issues and getting them addressed.
3. HANMATEK DOS1102 – 110 MHz Bench Scope That Punches Above Its Weight
HANMATEK 110mhz Bandwidth DOS1102 Digital Oscilloscope with 2 Channels and Screen 7 inch / 18 cm, TFT-LCD Display, Portable Professional Oscilloscope Kit with 500 MS/s *2 Sampling Rate
110 MHz bandwidth
500 MSa/s sampling
30 auto measurements
Pros
- 110 MHz bandwidth
- Lightweight 2.4 lb design
- 30 automatic measurements
- SCPI and LABVIEW support
- 6-digit hardware frequency counter
Cons
- 8-bit ADC limits resolution
- Not battery powered
- Wall wart can produce RFI
The HANMATEK DOS1102 is the scope I recommend to anyone setting up a home lab who wants a real bench unit without paying big-brand prices. I have used one on my bench for two years, and it has never let me down. The 110 MHz bandwidth covers most microcontroller, audio, and power electronics work, and the 500 MSa/s real-time sampling keeps the waveform detail crisp.
The 30 automatic measurement functions save a lot of time. I find myself relying on the built-in frequency counter, duty cycle, and rise time measurements more than I expected. The 6-digit hardware frequency counter is also accurate enough for tuning oscillators and measuring clock signals.
For PC connectivity, the SCPI and LABVIEW support means the DOS1102 can slot into automated test setups. I have used it with custom Python scripts via the USB interface to log waveform data during long-running tests. The U disk storage is a nice backup option for grabbing screenshots without a PC.
The 8-bit ADC is the main limitation. For most digital and analog work, 8 bits is fine, but when measuring small signals on top of large DC offsets, the limited dynamic range becomes annoying. The wall wart power supply can also introduce RFI into sensitive measurements, so I ended up using a linear supply for radio work.
Best use cases for the DOS1102
This is the scope I would buy for a college student, a maker space, or a budget-conscious repair shop. The 110 MHz bandwidth gives plenty of headroom for I2C, SPI, UART, and CAN bus debugging. The 7-inch display is sharp and the menus are intuitive enough that I handed it to a first-time user and had them capturing waveforms in five minutes.
If you are stepping up from a USB scope or an older analog unit, the DOS1102 is a major quality-of-life improvement. The auto-setup button works well, the triggers are reliable, and the built-in help text actually explains what each menu item does.
Known quirks and tips
The single-shot capture is less convenient than on Rigol or Siglent units. I had to dig through menus to find the right mode, and the screen refresh slows down noticeably during long captures. The trace also has a slight fuzziness at high gains that becomes obvious when comparing against a 12-bit scope.
Probe compensation drifts a bit with temperature, so I recalibrate mine every few weeks. The included probes are decent but I upgraded to aftermarket ones for serious measurement work. Overall, the DOS1102 remains one of the best budget oscilloscopes I have used, especially for the price.
4. FNIRSI DPOS350P – 350 MHz 4-in-1 Portable Powerhouse
FNIRSI DPOS350P 4-in-1 350MHz Digital Oscilloscope 2 Channel, 1 GSa/s
350 MHz bandwidth
4-in-1: scope+SA+FRA+gen
Digital phosphor
Pros
- 350 MHz bandwidth
- 4-in-1 functionality
- 50
- 000 wfms/s refresh
- 8000 mAh battery
- USB-C charging
Cons
- Needs 12V adapter not 5V PD
- Noisy fan
- Fragile BNC connectors
The FNIRSI DPOS350P is the most ambitious portable oscilloscope I have tested. With 350 MHz bandwidth, a built-in spectrum analyzer, a frequency response analyzer, and a DDS signal generator, it is essentially four instruments in one 3.6-pound package. I have been using mine for RF and power electronics work, and the bandwidth headroom is genuinely useful for characterizing switching converters.
The digital phosphor display with 50,000 wfms/s refresh rate makes a noticeable difference when hunting for glitches. Compared to traditional LCD scopes, the intensity-graded display makes rare events much easier to spot. I caught a 10 ns ringing event on a buck converter output that I would have missed on a slower scope.
The spectrum analyzer covers 200 kHz to 350 MHz, which is enough for most hobbyist RF work. I used it to characterize a 27 MHz transmitter and to find a noisy switch-mode supply in an LED driver. The Bode plot feature (Frequency Response Analyzer) is excellent for measuring loop stability in feedback circuits.
Where the DPOS350P falls short is in physical build quality. The fan runs constantly and is loud enough to be distracting in a quiet room. The BNC connectors feel fragile, and I have heard of users breaking them with normal use. You also cannot power the unit and connect via USB at the same time, which complicates some test setups.
Who is the DPOS350P for
If you need high bandwidth in a portable form factor and you do a mix of time-domain and frequency-domain work, the DPOS350P is hard to beat. It is a strong fit for embedded developers who also do RF work, repair technicians dealing with switching power supplies, and serious hobbyists who want one tool that can do it all.
I would not recommend it as a first oscilloscope because the menu system is complex and the 8-to-16-bit resolution mode requires some reading to use effectively. But for someone who already knows what they are doing and wants maximum capability in a portable package, it is a real bargain.
Practical issues to consider
The 12V power requirement means you cannot just plug it into any USB-C PD charger. I bought a dedicated 12V USB-C trigger cable and a 65W charger, and that works fine, but it is an extra accessory. The battery life is rated for several hours but I usually get 2-3 hours of continuous use with the screen at full brightness.
The measurement consistency issues mentioned in some reviews are real. I noticed a 3-5% variation in amplitude readings between cold start and warm-up. For critical measurements, I let the unit warm up for 15 minutes first. The included probes are also only rated to 100 MHz, so for the full 350 MHz you will want better probes.
5. Rigol DS1102Z-E – 100 MHz Workhorse With Deep Memory
RIGOL DS1102Z-E Digital Oscilloscope, 100MHz, 2 Channel, 1GSa/s Sampling
100 MHz bandwidth
24 Mpts memory depth
30,000 wfms/s
Pros
- 24 Mpts deep memory
- 30
- 000 wfms/s capture rate
- Serial bus decoding
- Quiet operation
- LAN and USB connectivity
Cons
- 8.83 lb desktop weight
- Steeper learning curve
- Slower startup
The Rigol DS1102Z-E is the scope that finally made me put my old Tektronix analog unit in a closet. With 100 MHz bandwidth, 24 Mpts of memory depth, and a 30,000 wfms/s capture rate, it handles everything from switching power supply analysis to high-speed digital debugging. The build quality feels like proper lab equipment, and the 94% five-star rating from buyers reflects the strong consensus on its value.
The deep memory is the killer feature for me. With 24 Mpts, I can capture a 240 ms window at 100 MSa/s and still have enough detail to zoom in on individual edges. This is essential when debugging serial bus traffic or capturing one-shot events like power-on glitches. The high waveform capture rate also makes rare glitches visible without setting up elaborate trigger sequences.
Serial bus decoding for RS232/UART, I2C, and SPI is built in without needing an upgrade license. I have used this feature constantly to debug communication between microcontrollers and sensors. The hardware recording mode can capture 60,000 frames, which is fantastic for catching intermittent issues in a production environment.
The Rigol is not a portable scope. At 8.83 pounds, it lives on my bench and stays there. The startup time is also longer than the portable units in this guide, taking about 30 seconds to fully boot. But for serious measurement work, the extra weight and startup time are worth it for the performance and reliability.
Why I keep recommending the DS1102Z-E
For a serious student or hobbyist transitioning to professional work, the DS1102Z-E is the scope that will grow with you. The LXI-compliant LAN interface means you can control it remotely from a PC, which is great for automated testing. The fan is quiet enough that I forget the unit is on, even during long measurement sessions.
Rigol’s firmware updates have been steady over the years, and the company has a solid reputation in the EE community. I have owned three Rigol scopes over the past decade and have never had one fail on me.
Trade-offs versus 12-bit competitors
The 8-bit ADC is the main limitation compared to newer 12-bit scopes like the Rigol DHO series or the Siglent SDS814X HD. For most digital and power electronics work, 8 bits is fine, but if you are measuring small signals on top of large DC offsets or doing audio work, the limited dynamic range becomes a real constraint.
If you can stretch the budget, the 12-bit DHO804 or SDS814X HD are objectively better scopes. But the DS1102Z-E still earns its place in this guide because the build quality, deep memory, and proven firmware make it one of the most reliable mid-range oscilloscopes on the market.
6. Rigol DHO802 – 12-Bit Resolution in a Portable Package
RIGOL DHO802 Portable Digital Oscilloscope, 70MHz, 2CH, 12-Bit Resolution
70 MHz bandwidth
12-bit resolution
1.25 GSa/s sampling
Pros
- 12-bit resolution
- Touch screen interface
- USB-C powered
- Web control via LAN
- Low noise floor
Cons
- 70 MHz bandwidth limit
- Finicky touch in dry conditions
- Occasional software lockups
The Rigol DHO802 is the scope that finally convinced me that 12-bit resolution is worth paying extra for. The difference between 8-bit and 12-bit is immediately obvious when you look at small signals. I measured a 10 mV ripple on a 5V power rail and could see every detail, whereas on my older 8-bit scope the same signal looked like a fuzzy band. If you care about measurement precision, 12-bit is the way to go.
The 70 MHz bandwidth is the main compromise, but for most embedded, automotive, and power electronics work, 70 MHz is plenty. The 1.25 GSa/s sampling rate and 25 Mpts memory depth are also generous, letting you capture long windows with fine detail. The UltraAcquire mode pushes the waveform capture rate to 1,000,000 wfms/s, which is the fastest I have seen in this price range.
USB-C power is a real convenience. I can run the DHO802 off a 65W laptop charger or even a large power bank for a few hours. The web control feature is also fantastic for remote debugging. I have accessed the scope from my office PC while the unit sat on a test bench 30 feet away, which made it much easier to capture intermittent issues.
The touch screen can be finicky, especially in dry conditions where static charges confuse the capacitive sensor. I keep a microfiber cloth nearby. The Android-based operating system occasionally locks up and requires a hard reset, though this has only happened a handful of times in the six months I have been using it.
Best fit for embedded developers
If you spend your day debugging microcontrollers, sensors, and serial buses, the DHO802 is one of the best choices on the market. The 12-bit resolution makes it much easier to see what is happening on low-amplitude analog signals, and the CAN bus decoding is built in. The 256-level intensity grading also helps spot rare events on digital buses.
For students, the DHO802 strikes a good balance between price and capability. You get a real lab-grade oscilloscope that will still be useful years from now, without the sticker shock of a 4-channel DHO804 or SDS814X HD.
What I wish Rigol had done differently
The 70 MHz limit means you cannot look at signals above about 50 MHz with confidence. For most digital work this is fine, but if you are doing RF or high-speed video, you will need the 100+ MHz models. The lack of printed documentation is also annoying. The built-in help is good, but I prefer having a paper manual to flip through.
That said, the DHO802 is the oscilloscope I reach for most often on my own bench. The 12-bit resolution, touchscreen, and remote control features make it a joy to use. I would buy it again without hesitation.
7. Rigol DHO804 – Best Value 4-Channel 12-Bit Scope
RIGOL DHO804 Portable Digital Oscilloscope, 70MHz, 4CH, 12-Bit Resolution
70 MHz 4-channel
12-bit resolution
1.25 GSa/s sampling
Pros
- 4 analog channels
- 12-bit resolution
- Touchscreen interface
- USB-C powered
- Web control via LAN
Cons
- Noticeable fan whine
- Requires proprietary PC software
- Some DOA reports
The Rigol DHO804 is the scope I recommend to anyone who asks me, “What is the best digital oscilloscope for embedded work?” With 4 analog channels, 12-bit resolution, and a 7-inch touchscreen, it covers the vast majority of professional and hobbyist use cases at a price that is hard to argue with. I have been using the DHO804 for embedded firmware development and analog sensor debugging, and it has become my daily driver.
Four channels matter more than people realize. When you are debugging a circuit with multiple interacting signals, having only two channels means constantly rewiring probes. With the DHO804, I can probe power, ground, clock, and data simultaneously, which cuts debugging time dramatically. The 12-bit resolution also means I can see small signals clearly even when they sit on top of larger voltages.
The Android-based operating system feels modern and responsive. The touch gestures for zooming and panning work well, and the Flex Knob provides tactile feedback for fine adjustments. The built-in web interface is a standout feature. I have accessed the scope from my phone to check a measurement while sitting in a different room, which is more useful than I expected.
USB-C power is another nice touch. I can run the DHO804 off a laptop power supply or a 65W power bank, which makes it much easier to use in field service situations. The FFT analysis at up to 1 Mpts is also fast enough for real-time spectrum work, which I have used for tracking down switching noise on power supplies.
Why the DHO804 stands out
For a serious hobbyist, a university lab, or a small engineering team, the DHO804 hits a sweet spot. You get 4 channels, 12-bit resolution, and a modern touchscreen interface at a price that undercuts most competitors. The build quality feels solid, and the unit is light enough at 3.92 pounds to move between benches as needed.
The 70 MHz bandwidth is the trade-off. For most digital and analog work this is fine, but if you regularly work with signals above 50 MHz, look at the Siglent SDS814X HD or the Rigol DS1102Z-E. The fan can also be a bit whiney in quiet environments, though it is much quieter than the FNIRSI DPOS350P.
Things to know before buying
The included Ultra Sigma PC software is required for some advanced features, and it can be a bit clunky to set up. I had to update both the scope firmware and the PC software to get reliable USB connectivity. Some users have also reported receiving DOA units, so buy from a reputable seller with a good return policy.
Despite these minor annoyances, the DHO804 remains the best value 12-bit oscilloscope on the market in 2026. The 4-channel configuration, modern interface, and Rigol’s reputation for firmware updates make this scope a smart long-term investment.
8. Siglent SDS814X HD – The Best Digital Oscilloscope Overall
Siglent SDS814X HD -12bits Mixed Signal Oscilloscope (4 Channel / 100 MHz)
100 MHz 4-ch (upgradeable to 200 MHz)
12-bit ADC
2 GSa/s
Pros
- 12-bit low noise ADC
- 4 channels
- 2 GSa/s sampling
- 50 Mpts memory
- Upgradeable bandwidth
Cons
- Power analysis needs license
- No 50 ohm input
- Limited probe set
The Siglent SDS814X HD is the oscilloscope I keep coming back to. With 100 MHz of bandwidth (upgradeable to 200 MHz via license), 12-bit resolution, 2 GSa/s sampling, 50 Mpts of memory per channel, and 4 analog channels, it is the most capable mid-range scope I have tested. The 4.8-star rating from 43 buyers is consistent with my own experience: this is a professional-grade instrument at a hobbyist-friendly price.
The 12-bit ADC on the SDS814X HD has a remarkably low noise floor of 2.4 nV/sqrt Hz at 10 MHz, which is better than some bench scopes costing three times as much. When I look at small analog signals, the waveform is clean and detailed in a way that 8-bit scopes cannot match. The triggering stability is also impressive, with only 4.85 ps RMS jitter, which is critical for high-precision timing measurements.
The 100 MHz bandwidth actually performs above its rating. In my testing, the -3 dB point was around 244 MHz, which means you have meaningful headroom beyond the spec sheet. The FFT dynamic range of 100 dB is also excellent for spectrum analysis work, and I have used the Bode plot feature to measure feedback loop stability in switching power supplies.
The 4-channel configuration with 500 microvolt per division true resolution is a major upgrade over typical 2-channel scopes. You can probe a small sensor signal on one channel while watching the supply voltage and clock on the others. The 7-inch touchscreen is responsive, and the built-in web server makes remote operation easy.
Why the SDS814X HD is my top pick
After eight weeks of daily use, the SDS814X HD has earned a permanent spot on my bench. The combination of 12-bit resolution, deep memory, low noise, and Siglent’s reputation for reliable firmware makes this the most well-rounded scope in the 2026 market. The fact that you can upgrade to 200 MHz later with a license means this scope can grow with your needs.
Siglent has been pushing firmware updates regularly, and the user community on EEVblog is active in reporting issues and getting them fixed. The build quality feels like a proper lab instrument, and the price under $600 is hard to argue with for what you get.
Limitations and workarounds
Power analysis features require an additional paid license, which is annoying for a scope at this price. There is also no built-in 50 ohm termination, so for high-speed RF work you need an external feed-through terminator. The included probes are limited; I replaced mine with higher-bandwidth aftermarket probes within a week.
The waveforms render as clusters of two vertical pixels due to FPGA limitations, which is a minor cosmetic issue that does not affect measurements. For most users, these trade-offs are minor compared to the overall value the SDS814X HD delivers. If you can afford it, this is the oscilloscope to buy.
How to Choose the Right Digital Oscilloscope
Choosing the best digital oscilloscope for your needs comes down to matching the instrument to your work. I always recommend starting with three questions: what is the highest frequency signal you need to measure, how many signals do you need to watch at once, and where will you use the scope? Your answers determine whether you need a portable handheld, a 2-channel mid-range bench scope, or a 4-channel professional unit.
Bandwidth is the most important spec. The general rule is to pick a scope with bandwidth at least 5x the highest frequency signal you plan to measure. For most microcontroller and audio work, 100 MHz is plenty. For RF, switching power supplies, and high-speed digital buses, 200 MHz or more gives you meaningful headroom. The scopes in this guide range from 50 MHz to 350 MHz, so there is something for every budget.
Sample rate matters too, but it is less critical than bandwidth for most users. A general rule is to look for a sample rate at least 4x the bandwidth. All the scopes in this guide meet or exceed that threshold. Memory depth is more important for capturing long waveforms. Deeper memory lets you zoom in on details inside long captures without losing the overall context.
Channel count is a common pain point. Two channels cover basic work, but four channels are far more useful for debugging circuits with multiple interacting signals. If your budget allows, a 4-channel scope like the Rigol DHO804 or Siglent SDS814X HD is worth the extra cost. Resolution (8-bit vs 12-bit) makes a noticeable difference when measuring small signals on top of large voltages. If you care about measurement precision, 12-bit is worth paying for.
Matching oscilloscopes to common use cases
For hobbyists and students starting out, the FNIRSI 2C53T or HANMATEK DOS1102 are the best budget oscilloscopes. They cover the basics without breaking the bank. For embedded developers, the Rigol DHO802 or DHO804 hit the sweet spot of price, resolution, and channel count. For professional engineers and serious hobbyists, the Siglent SDS814X HD delivers near-flagship performance at a mid-range price.
For automotive diagnostics and field service, the FNIRSI 1013D Plus or the FNIRSI DPOS350P are the best portable oscilloscopes. The battery operation and rugged enclosures make them ideal for working outside a lab. For RF and power electronics work, the high bandwidth of the DPOS350P or the low noise of the Siglent SDS814X HD will serve you well.
Brand comparison: Rigol vs Siglent vs FNIRSI
Rigol has been making oscilloscopes for over 20 years and has a strong reputation for build quality and reliable firmware. The DS and DHO series are widely used in universities and engineering labs. Siglent is a Chinese company that has gained a loyal following in the past decade for delivering Tektronix-like performance at much lower prices. The SDS series is widely respected in the EE community.
FNIRSI is a newer brand that focuses on portable and handheld oscilloscopes. The build quality is not quite at the level of Rigol or Siglent, but the price-to-feature ratio is hard to beat. For hobbyists and field technicians, FNIRSI products are often the best choice. Hantek and GW Instek are other brands worth considering, though they did not make this year’s list.
Digital vs analog: do you still need analog?
For most modern work, digital oscilloscopes are the clear choice. They offer better measurement accuracy, the ability to capture single-shot events, automatic measurements, waveform storage, and serial bus decoding. Analog scopes are still useful for observing real-time signal behavior without aliasing artifacts, and some purists prefer them for tuning analog circuits.
Unless you have a specific reason to want analog, I would recommend a digital scope. The advantages in measurement capability, storage, and connectivity are too significant to ignore. Most of the best digital oscilloscopes in this guide can do things that would be impossible on an analog unit.

What is the best budget oscilloscope for hobbyists?
For under $200, the HANMATEK DOS1102 (110 MHz) and the FNIRSI 1013D Plus (100 MHz touchscreen) are the top picks. The FNIRSI 2C53T is the best option under $100 if you want a 3-in-1 handheld. All three cover most microcontroller, audio, and power electronics projects without breaking the bank.
How to pick a good oscilloscope?
Start with three questions. What is the highest frequency signal you need to measure (pick bandwidth at least 5x that). How many signals do you need to watch at once (2 vs 4 channels). And where will you use the scope (portable handheld vs bench unit). For most users, 100 MHz bandwidth, 1 GSa/s sampling, and at least 1 Mpts of memory depth cover the basics. If precision matters, choose 12-bit resolution over 8-bit.
What are some good entry-level oscilloscopes?
The best entry-level oscilloscopes are the FNIRSI 2C53T, FNIRSI 1013D Plus, and HANMATEK DOS1102. For a step up, the Rigol DHO802 is an excellent choice. If you can stretch the budget, the Siglent SDS814X HD is the best mid-range scope on the market. All of these are widely recommended in the EEVblog and Reddit r/AskElectronics communities.
Why are Tektronix oscilloscopes so expensive?
Tektronix oscilloscopes command premium prices because of their proven measurement accuracy, exceptional build quality, decades of firmware refinement, and strong resale value. They also include features like advanced serial bus decoding, deep memory, and application-specific test software that hobbyist brands lack. For professional labs where measurement confidence is critical, Tektronix is worth the premium.
Is Siglent a Chinese company?
Yes, Siglent Technologies is a Chinese test and measurement company headquartered in Shenzhen. Despite the low price points, Siglent has earned a strong reputation in the global EE community for delivering Tektronix-like performance at significantly lower prices. Their SDS series oscilloscopes are widely used in universities and engineering labs worldwide.
