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
Rigol DHO802
Pros
- 12-bit ADC at $329 — the cheapest way to get modern 12-bit resolution from a major brand
- Same compact form factor and touchscreen as the rest of the DHO800 series
- 25Mpt memory depth is excellent for a scope at this price
- USB-C power means you can run it from a portable battery pack
- Protocol decoding for SPI, I2C, UART, and CAN included
- Modern Rigol UI — the same intuitive touchscreen experience as the DHO924S
Cons
- Only 2 channels — the biggest limitation for embedded debugging
- 70MHz bandwidth is adequate but not exciting
- Fan noise carries over from the DHO800 series
- For ~$120 more, the DHO804 adds 2 more channels which matters enormously
- No function generator
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.
Rigol DHO802
The Rigol DHO802 is the budget entry point to 12-bit oscilloscope territory, and at $329 it's genuinely compelling. You get the same modern touchscreen interface, 12-bit ADC, and compact form factor as the rest of the DHO800 series, just with 2 channels instead of 4. The 25Mpt memory and protocol decoding are both strong at this price. The honest question is whether 2 channels are enough for your work — if you're probing a single signal or doing basic Arduino debugging, absolutely. The moment you need to correlate clock and data lines on SPI, or monitor multiple signals simultaneously, you'll wish you had 4 channels. The DHO804 at ~$439 adds those extra channels, and for most users that $110 premium is worth paying upfront rather than regretting later.
