FNIRSI DST-201 3-in-1 handheld digital multimeter oscilloscope signal generator

The FNIRSI DST-201 is a handheld digital multimeter that combines three instruments in one: a True RMS multimeter, a handheld oscilloscope and a DDS signal generator. With a 1 MHz bandwidth and 5 MSa/s sampling rate, the oscilloscope displays waveforms in real time, making short glitches, spikes and jitter easy to spot. The signal generator outputs 13 waveform types from 0 to 10 kHz, with adjustable amplitude and duty cycle, which is useful for testing amplifiers, tuning filters or simulating PWM signals.

As a multimeter, it measures AC and DC voltage and current, resistance, capacitance, frequency, temperature, diodes and continuity. Waveform Hold and data logging functions help capture intermittent faults for later analysis. The 2.8-inch TFT display offers day and night modes, and the 3000 mAh battery charges via USB-C.

The package includes a P6100 oscilloscope probe, test leads, a crocodile clip probe, a USB cable and a user manual. The device weighs 733 g.
