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 DHO804
Pros
- 7-inch IPS touchscreen — same display as the DHO924S
- 25Mpt memory depth is solid for extended capture sessions
- Modern, intuitive interface makes learning easy
- 4 channels with protocol decoding (SPI, I2C, UART)
- WiFi connectivity for remote viewing and data export
Cons
- 70MHz bandwidth is the real compromise — limits this scope's ceiling
- No built-in function generator unlike the DHO924S
- 25Mpts memory is half the DHO924S's 50Mpts
- Stepping up to the DHO924S now costs substantially more
Our Verdicts
Hantek 6022BE
The Hantek 6022BE is the bare minimum USB oscilloscope — and I mean that literally, not as a compliment. At around $85, 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 sub-$100 ceiling and just need to verify signals exist, this will do — but you'll outgrow it fast.
Rigol DHO804
The Rigol DHO804 is the entry point to Rigol's DHO platform, offering the same 7-inch IPS touchscreen experience as the DHO924S with 70MHz bandwidth and 25Mpt memory at $439. For Arduino, basic analog work, and learning, 70MHz is genuinely sufficient — most signals you'll encounter stay well under this limit. The old objection was that the DHO924S cost almost the same; that is no longer true. With the DHO924S now priced like a premium scope, the DHO804 is the modern Rigol touchscreen pick for buyers who want a current interface without jumping near $900.
