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 DHO814
Pros
- 12-bit ADC — the Reddit community now considers this mandatory for new scope purchases
- Compact form factor is noticeably smaller and lighter than the DHO900 series
- Same modern touchscreen interface as the DHO924S — intuitive and responsive
- 100MHz bandwidth handles most hobbyist and embedded signals comfortably
- USB-C power input means you can run it from a power bank in the field
- CAN decoding included — Rigol doesn't always include this on lower-tier models
Cons
- Fan noise is a known complaint in the DHO800 series — audible in quiet rooms
- At ~$549, you're only $10 below the DHO924S which has 250MHz bandwidth
- 25Mpt memory is half the DHO924S's 50Mpts
- No built-in function generator
- The Siglent SDS804X HD offers similar 12-bit performance for $100 less at 70MHz
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 DHO814
The Rigol DHO814 is the mid-tier entry in Rigol's 12-bit DHO800 lineup, offering 100MHz bandwidth and 4 channels in a compact, USB-C-powered package. The 12-bit ADC is the real story here — the Reddit community has essentially made 12-bit resolution the new baseline for oscilloscope recommendations, and the DHO814 delivers. The compact form factor and power bank compatibility are genuine advantages over the larger DHO900 series. The uncomfortable truth is pricing: at ~$549, you're within striking distance of the DHO924S at $449 which gives you 250MHz bandwidth and 50Mpt memory. The DHO814 only makes sense if you specifically value the smaller size or find it on sale significantly below MSRP.
