Oscilloscope Signal Generator Fnirsi 1014D 2-in-1 — 100 MHz bandwidth, 1 GS/s sampling rate

The FNIRSI 1014D is a portable 2‑in‑1 test instrument combining a two‑channel digital oscilloscope and a DDS signal generator. It provides 100 MHz analog bandwidth with up to 1 GSa/s sampling, a 7‑inch 800×480 LCD, 1 MΩ input impedance per channel and an internal 1 GB memory capable of storing waveform and screenshot records. The device supports auto-analysis, FFT, X‑Y mode, cursor measurements and USB export for saved data.

Advantages

The instrument integrates oscilloscope and generator functions in one compact unit, allowing simultaneous signal analysis and generation. High sampling rate and 100 MHz bandwidth enable detection of short transients. The built‑in DDS generator offers multiple standard waveforms with 1 Hz frequency resolution and output up to 10 MHz for sine waves. A capture‑output function can reproduce stored oscilloscope waveforms as generator output, increasing testing flexibility. An automatic overvoltage protection module permits safe measurements up to 400 V when using a x10 probe. The 7" color LCD with intelligent trigger detection simplifies setup and the internal memory stores up to 1,000 waveforms and 1,000 screenshots for review and export.

How to use

Connect probes to the input channels and set the probe attenuation (1× or 10×) to match the expected signal amplitude. Power the unit via the USB power input and use the front‑panel controls or encoder to select time base, voltage scale and trigger mode. For signal generation, open the DDS generator menu, choose waveform type and set frequency and amplitude with 1 Hz resolution. Use the capture‑output function to record a waveform from the oscilloscope and replay it through the generator output. Save important waveforms or screenshots to internal memory and export files to a computer by USB when needed.

Recommendations

Use the x10 probe setting when measuring mains or other high‑voltage circuits to ensure overvoltage protection is active. For accurate timing and harmonic analysis, enable the highest feasible sampling rate and use the FFT mode. Regularly export and back up recorded waveforms if long‑term storage or external analysis is required.
