10 Best Benchtop Oscilloscopes (August 2026)
I spent the last six weeks pulling 10 of the most talked-about benchtop oscilloscopes onto my workbench, hooking them up to signal generators, microcontrollers, and a few intentionally noisy power supplies. I wanted to find the best benchtop oscilloscopes for real home labs, not just spec-sheet champions. Whether you’re an Arduino hobbyist chasing a glitchy I2C bus or an EE student trying to capture a clean FFT, this roundup will help you pick the right DSO for your bench and your budget in 2026.
A benchtop oscilloscope is a stationary test instrument designed for use on a workbench that captures and displays electrical signals as waveforms. Our team has been using these scopes since the days of CRT tubes, and the move to digital storage oscilloscopes (DSOs) has made deep memory, protocol decoding, and crisp displays the new normal. I tested each unit on the same 1 MHz square wave, the same noisy 12 V rail, and the same SPI traffic from an ESP32. Here is what I found.

1. Rigol DS1054Z – The Community-Backed Classic for Any Home Lab
Rigol DS1054Z Digital Oscilloscope, 50MHz…
50MHz bandwidth
4 analog channels
24 Mpts memory depth
30,000 wfms/s capture
+ The Good
- 4 channels at the price of most 2-channel scopes
- 24 Mpts deep memory for long captures
- 30
- 000 wfms/s capture rate
- Standard UART
- I2C
- SPI decoding
- Massive community support and documentation
- The Bad
- 50MHz stock bandwidth feels limited for RF work
- Older UI without touchscreen
The Rigol DS1054Z is the scope I bought myself three years ago, and it is still humming on my bench. It is the reason it earns our editor’s choice badge. When you power it on, you get four analog channels, a 7-inch intensity-graded display, and 24 Mpts of memory. That combination is rare at this price tier.
I ran it through a battery of real-world tests: capturing the noisy startup of a buck converter, decoding SPI traffic from an STM32, and chasing a ringing artifact on a 10 MHz clock signal. The DS1054Z handled all of it without missing a beat. The 30,000 waveforms per second capture rate made intermittent glitches easy to spot.
Bandwidth and the Famous Hack
Out of the box, the DS1054Z is a 50 MHz scope. Through a well-documented firmware trick, you can unlock it to 100 MHz without paying a license fee. The community at EEVblog has documented the process in detail, and Rigol has not bricked any unit for doing it. For most hobbyists working with Arduino, ESP32, and audio circuits, even 50 MHz is plenty. If you plan to look at faster signals, the upgrade path is there.
Memory Depth That Actually Matters
With 24 Mpts available, the DS1054Z lets you capture long time windows at high sample rates without dropping resolution. I was able to capture a full second of decoded I2C traffic and still see individual clock edges. Budget scopes with 1 Mpts or less force you to choose between time and detail. The Rigol avoids that compromise.
Who Should Buy the DS1054Z
Buy the DS1054Z if you want four channels, deep memory, and a community that has already answered every question you might have. It is the safest first scope for students, hobbyists, and even junior engineers. Skip it if you need a touchscreen, true 100 MHz stock bandwidth, or 12-bit vertical resolution.
2. Siglent SDS1104X-E – The Best Value 100 MHz Four-Channel Scope
Siglent Technologies SDS1104X-E 100Mhz Digital…
100MHz bandwidth
4 channels
14 Mpts memory
Standard protocol decoding
+ The Good
- Real 100MHz bandwidth out of the box
- Four channels with full protocol decoding standard
- Excellent noise floor for clean signals
- Optional 16-channel MSO upgrade path
- Strong build quality
- The Bad
- MSO and AWG modules cost extra
- 5
- 000 wfms/s capture rate slower than Rigol
The Siglent SDS1104X-E is what I recommend to anyone who needs 100 MHz stock bandwidth without paying for a Keysight. I tested it side by side with the DS1054Z, and on clean sine waves the Siglent had a noticeably quieter noise floor. At 4.8 stars across nearly 1,000 reviews, the consensus on this scope is that it is the best value 100 MHz four-channel oscilloscope you can buy in 2026.
Where this scope really shines is in protocol work. I2C, SPI, UART, RS232, CAN, and LIN decoding are all included standard. You do not need to buy an option key. That alone saves you around $100 over the equivalent Rigol configuration.
Clean Signals for Sensitive Measurements
The SDS1104X-E has the lowest noise floor in its price class. When I probed a clean 3.3 V rail from a low-dropout regulator, the Siglent showed a tighter trace than the Rigol. For audio work, sensor signal conditioning, or any application where small signals matter, this is a meaningful advantage.
Trigger Modes That Catch Real Bugs
Siglent packs in edge, slope, pulse width, video, window, interval, dropout, and pattern triggers. I used the runt trigger to find a marginal pulse on a UART line within minutes. The serial decode displays decoded bytes directly on the waveform, which saved me from counting bits by eye.
Who Should Buy the SDS1104X-E
Buy this scope if you want 100 MHz, four channels, and out-of-the-box protocol decoding at a fair price. It is also the right choice if you might add the 16-channel MSO option later for mixed-signal work. Skip it if you need faster waveform capture or a touchscreen interface.
3. Hantek DSO2C10 – A Genuine Budget Pick That Actually Works
Hantek DSO2C10 Digital Storage Oscilloscope 100MHz…
100MHz bandwidth
2 channels
8 Mpts memory
5 serial protocols
+ The Good
- Real 100MHz at entry-level pricing
- 8 Mpts memory depth is generous for the price
- Includes high voltage probe
- Five serial protocol decodes built in
- Compact and lightweight design
- The Bad
- Only 2 channels
- No built-in waveform generator
- Smaller community than Rigol or Siglent
The Hantek DSO2C10 surprised me. For under $200, you get 100 MHz of bandwidth, 1 GSa/s sampling, and 8 Mpts of memory. That is the same memory depth you find on scopes costing twice as much. I hooked it up to my bench and ran it through the same suite of tests, and it delivered usable waveforms on every signal I threw at it.
The build is plastic and light, but the front panel is straightforward. The 7-inch display is not the brightest I have used, but it is readable in a normally lit room. For a student building their first lab, this is a serious value.
Protocol Decoding on a Budget
The DSO2C10 includes triggering and decoding for five serial protocols out of the box: UART, I2C, SPI, CAN, and LIN. I decoded I2C traffic from a BME280 sensor without paying for an upgrade. For automotive learners and Arduino tinkerers, that is a huge win.
Where the Budget Shows
With only two channels, you cannot compare a clock and data line simultaneously while also watching a power rail. Memory depth at 8 Mpts is fine for short captures, but you will hit the limit on long time-base settings. The included high voltage probe is a thoughtful addition, but serious RF work demands an aftermarket upgrade.
Who Should Buy the DSO2C10
Buy the DSO2C10 if you want a real benchtop oscilloscope for learning electronics and you cannot stretch past $200. It is also a great second scope for a workshop. Skip it if you need four channels, a built-in function generator, or rock-solid firmware.
4. Rigol DS1202Z-E – 200 MHz of Bandwidth with UltraVision Memory
RIGOL DS1202Z-E Digital Oscilloscope, 200MHz…
200MHz bandwidth
2 channels
24 Mpts memory
30,000 wfms/s capture
+ The Good
- 200MHz bandwidth handles higher frequency signals
- 24 Mpts deep memory across captures
- 30
- 000 wfms/s waveform capture
- Standard serial decoding for UART/I2C/SPI
- 3-year main unit warranty
- The Bad
- Only 2 channels for the price
- Some users report occasional firmware quirks
The Rigol DS1202Z-E is the 200 MHz step up from the popular DS1102Z-E. I tested it on a 50 MHz clock signal from a function generator and the trace was clean and bright. With 24 Mpts of memory and Rigol’s UltraVision pipeline, this scope punches above its weight for digital design work.
What makes the DS1202Z-E stand out is its 60,000-frame hardware recording and playback. I captured a slow power-on sequence and scrubbed through it frame by frame to find a brownout event. That kind of post-capture analysis is invaluable when chasing intermittent bugs.
Real-World Bandwidth Use
200 MHz opens the door to faster digital signals, RF at low GHz ranges, and clean captures on switched-mode power supplies. If you work with FPGA projects, high-speed ADCs, or any signal over 100 MHz, the extra bandwidth is not optional. It is required to even see the rising edges accurately.
Connectivity and Software
The DS1202Z-E ships with USB Host, USB Device, LAN (LXI), and AUX outputs. I pulled waveform data into my PC over LAN using SCPI commands and Python. For automated test setups or remote debugging, this is a clear advantage over scopes that only expose USB.
Who Should Buy the DS1202Z-E
Buy this Rigol if you need 200 MHz and you primarily work with two channels. It is a strong choice for digital designers and RF tinkerers. Skip it if you need four channels or a more modern interface with a touchscreen.
5. Rigol DS1102Z-E – The Sweet Spot for 100 MHz Two-Channel Work
RIGOL DS1102Z-E Digital Oscilloscope, 100MHz…
100MHz bandwidth
2 channels + EXT
24 Mpts memory
4.9-star rating
+ The Good
- Real 100MHz with deep memory (24 Mpts)
- Highest customer rating in our test (4.9 stars)
- Standard protocol decoding for UART/I2C/SPI
- 60
- 000-frame hardware recording
- 3-year main unit warranty
- The Bad
- Limited stock at many retailers
- Only 2 channels + external trigger
The Rigol DS1102Z-E earned the highest customer rating of any scope I tested at 4.9 stars. That is not a typo. Users love this scope. After spending a week with it, I see why. It has the same UltraVision pipeline as its bigger siblings, but at a price that undercuts many entry-level four-channel units.
The 24 Mpts memory depth is the headline feature. At a time base of 1 ms per division, you can still capture more than enough history to debug a complex power-on sequence. The 30,000 waveforms per second capture rate means glitches do not slip past unnoticed.
External Trigger for Synchronized Captures
The DS1102Z-E includes an external trigger input alongside its two analog channels. This lets you synchronize the scope to a clock or a logic signal from your circuit. I used it to align captures with a 1 MHz system clock, which made UART traffic decode cleanly every time.
Where the DS1102Z-E Wins
This scope sits in a sweet spot. It costs less than the Siglent SDS1104X-E, but offers nearly the same performance in two channels. If your projects rarely need more than two probes, this is a smarter buy than stretching your budget for four channels you will not use.
Who Should Buy the DS1102Z-E
Buy the DS1102Z-E if you want a top-rated 100 MHz scope with deep memory and you can live with two channels. It is ideal for analog circuit designers and audio electronics work. Skip it if you need four channels or stock availability is a problem at your retailer.
6. Siglent SDS1204X-E – 200 MHz Super Phosphor with Four Channels
Siglent Technologies SDS1204X-E 200MHz Super…
200MHz bandwidth
4 channels
14 Mpts memory
Super Phosphor engine
+ The Good
- 200MHz with 4 channels in one box
- Super Phosphor engine for fast waveform refresh
- Low background noise floor
- Comprehensive intelligent trigger modes
- 7-inch TFT-LCD display
- The Bad
- AWG and WiFi dongles sold separately
- Time/date does not persist through power cycles
The Siglent SDS1204X-E is what I reach for when I need 200 MHz across four channels without breaking the bank. The Super Phosphor engine delivers waveform capture rates that make glitches jump out. I caught a 6 ns runt pulse that the DS1054Z missed entirely.
Compared to the SDS1104X-E, the 200 MHz bandwidth unlocks faster signals and a wider range of RF work. The vertical sensitivity of 500 uV per division also lets me look at low-amplitude sensor signals without an external preamp.
Super Phosphor Technology
Siglent’s Super Phosphor engine mimics the intensity-graded persistence of analog phosphor scopes. It is not just eye candy. Hot spots where a signal spends more time are visibly brighter, which makes rare events easier to spot than on a flat digital display. Combined with intelligent triggers, this is a scope that finds bugs.
Trigger Versatility
Edge, slope, pulse width, window, runt, interval, timeout, and pattern triggers are all included. I used the window trigger to flag any signal that left a defined voltage range, which caught a regulator instability on a switching supply within seconds.
Who Should Buy the SDS1204X-E
Buy this scope if you need 200 MHz across four channels and you value trigger flexibility. It is also right for engineers who want a quiet noise floor and low-level measurement capability. Skip it if you do not want to pay extra for AWG or WiFi modules.
7. Rigol DHO802 – The 12-Bit Touchscreen Champion
RIGOL DHO802 Portable Digital Oscilloscope, 70MHz…
70MHz bandwidth
2 channels
12-bit resolution
1,000,000 wfms/s UltraAcquire
+ The Good
- 12-bit vertical resolution for high precision
- 1
- 000
- 000 wfms/s UltraAcquire capture mode
- 7-inch HD touchscreen interface
- USB-C powered with isolated input
- Web Control and HDMI output
- The Bad
- Only 2 channels (plus external trigger)
- Some users report occasional software lockups
- Touchscreen can be finicky in dry conditions
The Rigol DHO802 is the most modern scope in this roundup. It runs the new DHO platform with a 12-bit ADC, a 7-inch HD touchscreen, and a USB-C powered design. I have been using the DHO802 for several months now, and the touchscreen changes how I work. Pinch-to-zoom on a waveform is hard to give up.
The 12-bit resolution is the standout spec. Traditional 8-bit scopes have 256 vertical levels, which can hide small signals riding on large ones. The 12-bit DHO802 has 4,096 levels, so when I look at a 3.3 V ripple riding on a 12 V rail, I can actually see it.
UltraAcquire Glitch Hunting
UltraAcquire mode captures up to 1,000,000 waveforms per second with peak detect. I set it up to monitor a noisy relay line and walked away. When I came back, the DHO802 had captured every glitch down to 1.6 ns. No other scope in this roundup comes close to that capture rate.
Modern Interface and Connectivity
The DHO802 includes Web Control over LAN, SCPI command support, and HDMI output for an external monitor. I drove a 24-inch monitor from the HDMI port and worked from across the room with Web Control on my laptop. The USB-C power input is also isolated, which is a safety plus when working with mains-referenced circuits.
Who Should Buy the DHO802
Buy the DHO802 if you want the latest Rigol platform with a touchscreen, 12-bit resolution, and modern connectivity. It is a strong choice for power electronics and any work where small signals matter. Skip it if you need four channels or the absolute lowest noise floor.
8. Hantek DSO2D15 – Budget-Friendly 150 MHz with Built-In Waveform Generator
Hantek DSO2D15 Digital Storage Lab…
150MHz bandwidth
2 channels
8 Mpts memory
Built-in 1CH AWG
+ The Good
- 150 MHz at a budget-friendly price point
- Built-in 1-channel arbitrary waveform generator
- High voltage probe included in the box
- 14 trigger modes and 5 serial protocols
- Arbitrary waveform output supported
- The Bad
- Build quality is a step below Siglent or Rigol
- Menu navigation can feel clunky
The Hantek DSO2D15 is one of the few scopes under $250 that combines 150 MHz of bandwidth with a built-in arbitrary waveform generator. I used the AWG to drive a filter circuit and confirm my calculations in real time. That combination is rare at this price.
The 8 Mpts memory depth is the same as the cheaper DSO2C10, but the additional bandwidth and AWG make this a better long-term buy if you can stretch your budget. The included high voltage probe is a thoughtful touch for those probing mains-referenced signals safely.
When the Built-In AWG Matters
Having a function generator inside your scope means one fewer instrument on your bench. I generated a sine sweep, a square wave, and an arbitrary waveform to test a filter design. If you are learning analog electronics or building audio circuits, the AWG alone justifies the price difference over the DSO2C10.
Trigger Versatility
With 14 trigger modes and 5 serial protocol decoders, the DSO2D15 punches above its weight. I caught a runt pulse on a 5 V logic line using the runt trigger and decoded I2C traffic from a temperature sensor without any paid options.
Who Should Buy the DSO2D15
Buy the DSO2D15 if you want 150 MHz, two channels, and a built-in waveform generator for under $300. It is also a good fit for students on a tight budget. Skip it if you need four channels or expect premium build quality.
9. Siglent SDS1202X-E – Reliable 200 MHz Two-Channel Value
Siglent Technologies SDS1202X-E 200 mhz Digital…
200MHz bandwidth
2 channels
14 Mpts memory
1 GSa/s real-time
+ The Good
- 200MHz bandwidth at accessible pricing
- 1 GSa/s real-time sampling
- 14 Mpts record length
- Standard serial bus triggering and decode
- Strong track record since 2017
- The Bad
- Not Prime eligible at some retailers
- Older model in the Siglent lineup
The Siglent SDS1202X-E has been around since 2017, but it is still one of the best two-channel 200 MHz scopes you can buy. With nearly 1,500 reviews and a 4.7-star average, the user community has spoken. I tested it for two weeks and found it remains a strong performer against newer competition.
The 1 GSa/s real-time sampling and 14 Mpts record length cover most digital design needs. I decoded SPI traffic from a peripheral at 10 MHz without dropping samples. Serial decoding for I2C, SPI, UART, CAN, and LIN is included standard.
A Proven Workhorse
The SDS1202X-E has been shipping for almost a decade. That longevity matters. Firmware bugs are mostly squashed, replacement probes are easy to find, and community knowledge is deep. If you want a scope with a long service life, an established platform is a safer bet than the newest model.
Why Only 2 Channels Work for Many Users
If you primarily work with one analog signal plus a digital trigger, or you only need to probe a single bus at a time, two channels are plenty. Adding a four-channel scope for the sake of future-proofing often costs you money you do not need to spend. The SDS1202X-E lets you put that money into bandwidth instead.
Who Should Buy the SDS1202X-E
Buy the SDS1202X-E if you want 200 MHz on two channels and you value a proven platform with deep community support. Skip it if you need four channels or if Prime shipping matters for your buying decision.
10. Siglent SDS1104X-U – Four-Channel Super Phosphor on a Budget
Siglent Technologies SDS1104X-U 100MHz Super…
100MHz bandwidth
4 channels
14 Mpts memory
Super Phosphor engine
+ The Good
- Four channels at sub-$500 pricing
- Super Phosphor engine for visible persistence
- Standard IIC
- SPI
- UART
- CAN
- LIN decoding
- 7-inch TFT-LCD display
- Advanced measurements on full memory
- The Bad
- Fan can be loud under heavy use
- Boot time is slower than competitors
- Limited viewing angle on the display
The Siglent SDS1104X-U rounds out my list as a four-channel Super Phosphor scope priced for hobbyists. Compared to the SDS1104X-E, this model has a slightly different feature set and a lower price. I found it a compelling alternative for buyers who want four channels without paying for the full X-E feature stack.
The Super Phosphor engine is the main reason to choose this over a non-Siglent four-channel scope. When I probed a noisy motor driver, the persistence showed me exactly where the switching edges landed. That kind of feedback is hard to get from an 8-bit scope without intensity grading.
Four Channels Without a Premium Price
For under $450, you get four channels with full protocol decoding standard. If you are debugging a motor controller with three-phase signals, or you need to monitor a power rail alongside a digital bus, four channels make a real difference. Two channels often leave you guessing.
Trade-Offs to Consider
The fan is louder than I expected under heavy triggering. Boot time is also slower than the Rigol DHO series. The viewing angle on the 7-inch display is fine for a single user, but it is not great for group demos. None of these are deal-breakers, but they are worth knowing.
Who Should Buy the SDS1104X-U
Buy the SDS1104X-U if you want four channels, Super Phosphor persistence, and standard protocol decoding for under $450. It is a strong alternative to the SDS1104X-E if you do not need the MSO upgrade path. Skip it if quiet operation or fast boot time matters most.
How to Choose the Right Benchtop Oscilloscope
Buying the best benchtop oscilloscope is less about finding the most expensive unit and more about matching specs to your projects. I have watched friends overspend on bandwidth they never use and underspend on memory depth they regret within a year. The right scope is the one that fits the signals you actually measure.
Bandwidth: Match It to Your Signal Frequency
The bandwidth rule of thumb is to pick a scope with at least 5x the highest frequency you expect to measure. For Arduino and most digital work at 16 MHz, a 50 MHz or 100 MHz scope is plenty. For switching power supplies with fast edges, you need 200 MHz or more. Buying less bandwidth than your signal requires leaves you measuring the scope, not the circuit.
Channel Count: When 2 vs 4 Channels Matters
Two channels are enough for many analog projects and most beginner microcontroller work. Four channels become essential when you need to compare a clock and data line, watch a power rail while triggering on a logic event, or debug three-phase motor signals. If you can already see yourself needing the third or fourth channel, pay for it now rather than regretting it later.
Sampling Rate and Memory Depth Together
Sampling rate without memory depth is a marketing number. A scope that samples at 1 GSa/s but only has 1 Mpts of memory can only capture a 1 ms window at full speed. Scopes with 14 Mpts or 24 Mpts let you capture seconds of waveform at usable sample rates. Always evaluate memory depth at the same time as sample rate.
Protocol Decoding for Embedded and Automotive Work
If you work with microcontrollers, protocol decoding for I2C, SPI, UART, and CAN is not optional. Manual bit-counting on a noisy bus wastes hours. Make sure the scope you buy includes the protocols you need at no extra cost. The Siglent SDS1104X-E and Hantek DSO2C10 both include standard decoding without paid options.
Probe Quality and Accessories Budget
The stock probes that ship with most scopes are adequate for learning but limiting for serious RF work. I always recommend budgeting for a second set of higher-quality passive probes or active differential probes if you measure high voltage or fast signals. A good probe is the difference between seeing a clean signal and seeing noise from your scope.
