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
Siglent SDS1202X-E
Pros
- 200MHz bandwidth — 4x the stock DS1054Z at nearly the same price
- 14Mpt memory depth is excellent for capturing long waveforms
- Protocol decoding includes CAN and LIN — Rigol charges extra for these
- SPL (Siglent Programming Language) for scripting and automation
- Serial decode is free, not locked behind a paid license
Cons
- Only 2 channels — the fundamental tradeoff versus the DS1054Z
- Interface is less intuitive than Rigol's — steeper learning curve
- Smaller community means fewer tutorials and answered questions online
- No touchscreen — button-heavy navigation
- 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.
Siglent SDS1202X-E
The Siglent SDS1202X-E is the DS1054Z's biggest competitor, and it wins on raw specs: 200MHz bandwidth, 14Mpt memory, and protocol decoding that includes CAN and LIN without paying for licenses. The catch is you only get 2 channels, and that trade-off matters more than it sounds. When you're debugging SPI with clock, data, and chip-select lines all running, or trying to correlate an analog signal with a digital trigger, you'll wish you had 4 channels. If you work primarily with audio circuits, RF signals, or single-channel measurements, the 200MHz bandwidth is genuinely useful and this scope makes complete sense. For general embedded debugging with multiple signals, I'd take the DS1054Z's 4 channels over the extra bandwidth.
