◆ Overview
The FNIRSI 1014D is a two-channel oscilloscope with 100MHz bandwidth, a 1GSa/s maximum sample rate, 240 Kpts of memory, a 7-inch display, and a built-in signal generator. Its combination of a large display and generator makes it a self-contained option for learning and basic bench measurements.
◆ Pros & Cons
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

◆ Core Oscilloscope Specifications
FNIRSI specifies two channels, 100MHz bandwidth, and a 1GSa/s maximum sample rate for the 1014D. Those specifications cover many introductory electronics and low-frequency signal-viewing tasks.
The 240 Kpts memory depth is the key capture constraint. Longer time spans require a tradeoff between capture duration and sample density, so buyers who need deep zoomable records should compare memory depth carefully.
◆ Display and Controls
The 7-inch display gives waveforms and measurements more room than pocket-size handheld instruments. The tablet-style layout can move between work areas while providing a larger viewing surface for bench measurements.
◆ Built-In Signal Generator
The built-in signal generator is useful for producing a known source while learning time-base, voltage-scale, and trigger controls. It also reduces the need for a separate generator during basic circuit exercises.
The 1014D does not provide protocol decoding. Serial-data work therefore requires manual waveform interpretation or a separate decoding tool.
◆ Who Should Consider It
Consider the FNIRSI 1014D when two channels, 100MHz bandwidth, a 1GSa/s maximum sample rate, 240 Kpts of memory, a 7-inch display, and a built-in generator match the task. Choose a deeper-memory instrument for long captures, and choose a scope with documented decoding when serial-bus analysis is required.
Our Verdict
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.
