Pros & Cons
FNIRSI 1014D
Pros
- Affordable entry point at ~$115
- Built-in function generator is rare at this price
- Portable tablet form factor with battery backup
- Touchscreen interface is genuinely intuitive for beginners
- 100MHz bandwidth is impressive for an $80 scope
Cons
- 240Kpt memory depth is dangerously shallow — you'll hit this limit fast
- Build quality is plasticky; the corners flex under light pressure
- Calibration and accuracy lag well behind established brands
- No protocol decoding — can't decode SPI or I2C
- Firmware updates have been inconsistent
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
FNIRSI 1014D
The FNIRSI 1014D is one of the cheapest ways to get a real oscilloscope on your bench. At around $115, it's hard to complain about 100MHz bandwidth and a built-in signal generator — both of which would cost more from Hantek. The honest limitation is the 240Kpt memory depth, which is genuinely painful the moment you try to capture anything longer than a few milliseconds at full sample rate. I'd call this a learning tool, not a precision instrument. If you just want to see what your Arduino signals look like and learn what triggering means, it's a solid starting point. But if you need to trust your measurements or capture serial transactions, save up for a Rigol or Siglent — you'll thank yourself later.
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.
