FNIRSI DS215H Plus

FNIRSI DS215H Plus is a compact dual-channel digital oscilloscope with an integrated DDS function signal generator, designed for electronics development, repair, laboratory measurements and technical diagnostics. Key advantages of this model include a dual-channel 50 MHz oscilloscope, real-time sampling rates up to 250 MSa/s, an integrated DDS function generator with 13 output waveform types, a 3.5-inch IPS colour display, input protection up to ±400 V, and the ability to save waveforms and screenshots. Integrating both an oscilloscope and a signal generator into a single compact device allows convenient signal analysis and testing without the need for additional laboratory equipment. The "Plus" designation indicates the extended package version – according to the manufacturer's official specifications, the hardware characteristics are identical to the standard DS215H model, with the differences related to the supplied accessories.
