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 DS1104Z-S Plus
Pros
- 100MHz bandwidth with 4 channels — no bandwidth hack needed
- Built-in 25MHz function generator saves desk space and cost
- Same excellent trigger set as the DS1054Z
- Protocol decoding (SPI, I2C, UART) included
- Proven platform for teaching labs that need scope plus signal generator
Cons
- At ~$549, the DHO924S delivers more for $100 less
- Same dated interface as the DS1054Z — no touchscreen
- No WiFi or CAN/LIN decoding at this price
- The DS1000Z platform is aging compared to the DHO series
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 DS1104Z-S Plus
The DS1104Z-S Plus is the DS1054Z with the limitations officially removed: full 100MHz bandwidth and a built-in 25MHz function generator. At ~$549, it's the premium version of a proven platform that has a decade of community support behind it. The problem in 2026 is the Rigol DHO924S — it costs $100 less, has 250MHz bandwidth, a 7-inch IPS touchscreen, WiFi, 50Mpt memory, and is generally a better scope in almost every way. The DS1104Z-S Plus's advantage is its established reliability and the integrated function generator, which the base DHO924S also includes. I'd only choose this over the DHO924S if you're buying for a teaching lab with specific software integration requirements, or if you specifically need the proven DS1000Z platform.
