Pros & Cons
FNIRSI DPOX180H
Pros
- Very affordable at ~$110 for what it packs
- 180MHz bandwidth in a genuinely pocket-sized device
- Battery powered and truly portable — shirt-pocket size
- Built-in function generator and multimeter
- Protocol decoding for UART, SPI, and I2C
Cons
- 28Kpt memory depth is critically shallow — limits capture usefulness significantly
- 2.8-inch screen is very small — detailed waveform analysis is uncomfortable
- 500MSa/s sample rate is modest even for a pocket scope
- Accuracy concerns typical of FNIRSI at this price tier
- Build quality is mediocre — the housing feels flimsy
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
Our Verdicts
FNIRSI DPOX180H
The FNIRSI DPOX180H is a pocket oscilloscope with surprisingly high bandwidth for the money — 180MHz in something smaller than a deck of cards is legitimately impressive. At $110, you also get protocol decoding, a function generator, and a multimeter in the same device. The hard truth is the 28Kpt memory depth and 2.8-inch screen kill its usefulness for anything beyond quick spot checks — you can glance at a signal, but capturing and analyzing a long serial transaction is off the table. The OWON HDS2202S is better in almost every meaningful way if portability is your goal, but it costs $439 versus this scope's $110. At this price, the DPOX180H is best understood as a capable probe-and-check tool, not a primary bench instrument.
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.
