Pros & Cons
Hantek 6022BE
Pros
- Cheapest USB oscilloscope that actually works
- Tiny and portable — fits in a laptop bag or jacket pocket
- Works with open-source OpenHantek software (much better than official drivers)
- Bus-powered via USB — no wall adapter needed
- 1Mpt memory depth is genuinely decent for this price
Cons
- Only 20MHz bandwidth — severely limiting for most real work
- 48MSa/s sample rate means aliasing starts well below 20MHz
- Requires a PC to operate — useless in the field without a laptop
- Bundled software is mediocre; use OpenHantek instead
- No protocol decoding of any kind
Siglent SDS2104X Plus
Pros
- 200Mpt memory depth is exceptional — capture minutes of data at full sample rate
- 10.1-inch IPS touchscreen is genuinely gorgeous to work with
- 2GSa/s sample rate handles fast signals better than 1GSa/s scopes
- Comprehensive protocol decoding including FlexRay, I2S, and MIL-STD-1553
- Built-in 25MHz AWG function generator
- Feels like a professional instrument — because it is one
Cons
- At ~$1,099, it's at the top of hobbyist budgets
- 100MHz bandwidth is surprisingly low for this price tier
- Large and heavy — needs permanent bench space
- Overkill for casual Arduino projects or simple bench work
Our Verdicts
Hantek 6022BE
The Hantek 6022BE is the bare minimum USB oscilloscope — and I mean that literally, not as a compliment. At ~$65, you get 2 channels and 20MHz of bandwidth piped through your laptop screen, which is enough to verify that a PWM signal exists or check audio frequencies. The 20MHz limit is genuinely painful: you can't reliably see rise times on 3.3V Arduino signals, and anything SPI-related at normal speeds is already at the edge of what this scope can resolve. Skip the official software and use OpenHantek instead — it's actively maintained and much better. If you can stretch to the Analog Discovery 3, the difference is night and day. If you're truly at a $65 ceiling and just need to verify signals exist, this will do — but you'll outgrow it fast.
Siglent SDS2104X Plus
The Siglent SDS2104X Plus is a professional-grade scope that happens to be affordable enough for serious hobbyists, and using it for a long debugging session makes the price feel justified. The 200Mpt memory depth is the headline — you can capture minutes of data at full sample rate, then scroll back and zoom into any moment without re-triggering. The 10.1-inch IPS touchscreen is excellent. The comprehensive protocol decoding (including FlexRay and I2S) makes it the right tool for serious automotive or audio embedded work. The surprise is that all this comes with only 100MHz bandwidth — you're paying for depth, features, and build quality, not raw frequency response. At $1,099, this is a serious investment. It only makes sense if you do electronics work regularly enough to amortize that cost, and if you want an instrument you genuinely won't outgrow.
