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 SDS804X HD
Pros
- 12-bit ADC with what Reddit considers a cleaner analog front-end than Rigol — LeCroy heritage shows
- 2GSa/s sample rate is genuinely faster than the DHO804's 1.25GSa/s
- 50Mpt memory depth matches the DHO924S and doubles the DHO804
- CAN and LIN decoding included free — Siglent's standard generosity on protocols
- 70MHz bandwidth is unlockable to 200MHz via software license — massive upgrade path
- 7-inch capacitive touchscreen with responsive multi-touch gestures
Cons
- 70MHz stock bandwidth is limiting — you're paying for the upgrade path, not the base spec
- No built-in function generator (optional add-on)
- Siglent's community is smaller than Rigol's — fewer tutorials and forum answers
- At ~$438, you're close to the DHO924S at $449 which has 250MHz stock bandwidth
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 SDS804X HD
The Siglent SDS804X HD is THE competitor to the Rigol DHO804 that Reddit can't stop debating. On paper, 70MHz for $438 looks underwhelming — but the real story is Siglent's 12-bit ADC implementation, which the community consistently praises as having a cleaner noise floor than Rigol's, thanks to Siglent's LeCroy heritage in analog front-end design. The 2GSa/s sample rate and 50Mpt memory depth are both better than the DHO804. The bandwidth unlock to 200MHz via software license is the ace up its sleeve — it turns a $438 scope into a legitimate 200MHz instrument for an additional fee. If you value measurement quality over raw bandwidth numbers, this is the 12-bit scope to buy. If you just want the most bandwidth per dollar, the DHO924S at $449 with 250MHz is hard to argue against.
