Pros & Cons
FNIRSI 1014D
Pros
- Affordable entry point around $170
- 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 a sub-$200 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 DHO924S
Pros
- 250MHz bandwidth with 4 channels and a modern touchscreen workflow
- 7-inch IPS touchscreen with 1024x600 resolution — sharp and responsive
- 50Mpt memory depth for extended captures
- Built-in function generator and WiFi connectivity included
- Modern phone-like interface has almost no learning curve
- Protocol decoding for SPI, I2C, UART, CAN, and LIN
Cons
- 1.25GSa/s sample rate could be higher given the 250MHz bandwidth
- Newer platform means less community documentation than the DS1054Z
- Some early firmware bugs have been reported — check version before updating
- Fan can be audible in a quiet room
Our Verdicts
FNIRSI 1014D
The FNIRSI 1014D is one of the cheapest ways to get a real oscilloscope on your bench. At around $170, it's hard to complain about 100MHz bandwidth and a built-in signal generator — both of which would cost more from many established bench-scope brands. 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 DHO924S
The Rigol DHO924S is no longer the default hobbyist oscilloscope recommendation now that Amazon pricing is around $899. The 7-inch IPS touchscreen is still excellent — pinch to zoom, tap to place cursors, swipe to scroll through captures — and the spec stack is serious: 250MHz bandwidth, 4 channels, 50Mpt memory, a function generator, WiFi, and CAN/LIN protocol decoding. But at this price it belongs in the premium-upgrade tier, not the beginner tier. Buy it if you need the bandwidth, mixed-signal-ready feature set, and modern Rigol workflow. Most first-time buyers should start with the DS1054Z or DHO804 instead.
