Are you setting up a small electronics bench and wondering whether you need both an oscilloscope and a signal generator? The FNIRSI 1014D pairs them in one unit: a 2-channel digital storage oscilloscope with a built-in DDS signal generator, a 7-inch TFT LCD, and a listed price of USD 158.00.
Quick verdict
The FNIRSI 1014D is a practical 2-in-1 if you want to measure and generate signals from the same desktop device. It offers 100MHz analog bandwidth on each channel, a real-time sampling rate of 1GSa/s, and a 7-inch screen. The built-in signal generator adds 14 standard function signals with 1Hz frequency steps, which is useful for audio circuits, control signals, and general prototypes.
Who it suits
This unit suits hobbyists and repair-minded users who want a compact bench setup rather than several separate boxes. The built-in generator can feed test signals while the scope displays the result, so you can trace a signal path with one device instead of coordinating separate equipment.
What stands out from the listed details
- Chopping output: The described chopping function can take part or all of a signal captured by the oscilloscope and use it as the generator output. With space for up to 1000 customized cut-off signals, you can replay interesting captured segments as test signals.
- Protection and inputs: The built-in high-voltage protection module is rated for up to 400V continuous voltage, and the input resistance is listed at 1MΩ with AC/DC coupling. That combination is useful when moving between low-voltage logic and higher-voltage supply rails.
- Time base scale: The horizontal time base range goes from 50S/div to 10nS/div, so you can view everything from slow sensor signals to faster digital edges.
- Documentation: A USB picture export port lets you save screen captures.

The strongest reason to choose this FNIRSI 1014D is the convenience of having both an oscilloscope and a DDS signal generator in one package, so you can apply a signal and look at the result without a second piece of gear. The most noticeable limitation in the listed specifications is the 8-bit ADC precision, which means very small amplitude variations will be harder to distinguish; for many repairs and learning projects that is an acceptable trade-off, but it is worth knowing before you buy.
Meaningful trade-offs
The 8-bit ADC precision is enough to analyze waveform timing, shape, and amplitude at a basic level, but finer voltage details like low-level ripple or subtle noise may not be clearly resolved. The design is also limited to 2 channels, so if you need to compare several points at once you will have to probe them in pairs. The overall feature set is aimed at general-purpose work rather than high-resolution measurement.
Bottom line
If you need an oscilloscope and a signal generator on a single compact unit, the FNIRSI 1014D delivers that combination at USD 158.00. Its 100MHz bandwidth, 1GSa/s sampling, and the extra chopping output make it a complete setup for bench work. Just keep the 8-bit ADC precision in mind and match it to the signals you plan to measure.
