Pros & Cons
FNIRSI 1014D
Pros
- Affordable entry point around $170
- Built-in function generator is rare at this price
- 7-inch touchscreen in a portable tablet form factor
- 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
OWON HDS2202S
Pros
- Two oscilloscope channels with 200MHz bandwidth
- 1GSa/s maximum sample rate
- Built-in digital multimeter
- Built-in waveform generator
- Manufacturer-stated battery runtime of 3–6 hours
Cons
- 8 Kpts memory limits long waveform captures
- Only 2 oscilloscope channels
- Only Edge triggering is documented for this model
- No documented serial-protocol decoding
- 3.5-inch display is smaller than typical benchtop displays
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.
OWON HDS2202S
The OWON HDS2202S combines two 200MHz oscilloscope channels, a 1GSa/s maximum sample rate, a digital multimeter, and a waveform generator in a handheld instrument. OWON states a 3–6-hour battery runtime. Its documented 8 Kpts memory and Edge trigger make it most appropriate for portable signal checks rather than deep captures or serial-bus analysis.
