FNIRSI DS215H 2-in-1 Dual Channel 50MHz 250MS/s Oscilloscope Function Generator

The FNIRSI DS215H combines a dual-channel digital oscilloscope with 50 MHz analogue bandwidth and a function generator in one compact unit, so signal analysis and signal generation can be handled with a single device. Real-time sampling of up to 250 MSa/s captures waveforms accurately, including brief changes in the signal. The function generator covers 0 to 50 kHz, adjustable in 1 Hz steps, and its frequency, amplitude and duty cycle can all be set freely.

A 3.5-inch colour IPS display with 480 × 320 pixels shows the waveforms clearly. Settings are changed with a rotary knob and buttons, and screenshots can be saved for later review and documentation. The meter supports input voltages up to ±400 V and can be switched between 1X and 10X probe ratios.

Weighing 413 g and powered by a built-in 1500 mAh lithium-ion battery offering up to four hours of continuous operation, the instrument suits both workshop and field use. It charges via USB-C.
