Portable Oscilloscope Fnirsi 1013D 7" 100 MHz bandwidth 1 GSa/s sample rate

The Portable Oscilloscope FNIRSI 1013D is a battery-powered handheld oscilloscope with a 7" capacitive touch TFT display (800 x 480), two input channels, 100 MHz analogue bandwidth and up to 1 GSa/s sampling rate. It is intended for signal analysis, troubleshooting and design tasks in workshops, field diagnostics and electronics development. The unit includes automatic one-button signal adjustment, waveform recording and internal storage for quick capture and export of measurements via USB.

Advantages

The FNIRSI 1013D combines a clear 7" touchscreen with dual-channel measurement capability, allowing simultaneous comparison of two signals. Automatic one-button setup and an integrated waveform manager simplify routine measurements and data handling. Built-in surge protection up to 400 V (10X) and a 6,000 mAh battery providing approximately 4 hours of operation support safe and portable use. The device also offers a full set of trigger modes and cursor measurements for precise waveform analysis.

How to use

Connect probes to the input channels and set the probe attenuation (1X/10X) as required. Power on the oscilloscope and use touch controls to adjust time base and vertical scale; press the one-button auto-adjust to center and scale an incoming signal automatically. Use cursor measurement functions to read amplitude, period and frequency directly from the display. Store waveforms or screen images to internal memory and export them to a computer via USB when further analysis is needed.

Usage recommendations

Use the 10X probe setting when measuring higher voltages to utilize the full 400 V surge protection. Keep probe ground leads as short as possible to reduce noise and ground-loop effects. For repetitive transient capture, use Single trigger mode; for continuous monitoring, use Auto mode. Charge the device using the specified USB-C input and observe the stated input ranges and probe ratings to avoid measurement errors or damage.
