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 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 ~$699, it is no longer the obvious value play next to newer touchscreen scopes
- 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 $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 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 ~$699, it's the premium version of a proven platform that has a decade of community support behind it. The problem in 2026 is that newer touchscreen scopes have made the DS1000Z platform feel dated. The DHO924S costs more now, but it brings 250MHz bandwidth, a 7-inch IPS touchscreen, WiFi, 50Mpt memory, and a much more modern workflow. I'd only choose the DS1104Z-S Plus if you're buying for a teaching lab with specific software integration requirements, or if you specifically need the proven DS1000Z platform.
