Looking for a universal tool for electronics service, automotive diagnostics, or work in switchboards/control cabinets? FNIRSI DST-201 combines classic measurement with the ability to instantly “see” the signal on the screen, and also actively inject test waveforms into the circuit. This helps you identify spikes, fluctuations, interference, and intermittent faults faster.
The built-in oscilloscope (1 MHz / 5 MSa/s) offers Auto/Normal/Single modes, triggering, the Infinite Afterglow effect, and Waveform Hold to capture short events. The recording function and Curve Mode allow you to monitor value trends over time in a graph and easily spot power-supply or signal instability.
The DDS signal generator with 13 waveforms (e.g., sine, square, sawtooth, half-wave, step) helps when testing amplifiers, filters, or simulating PWM without additional equipment. True RMS mode ensures reliable measurements for both undistorted and distorted waveforms, and the color 2.8" TFT display with day/night themes keeps readability in any conditions.
