FNIRSI DS215H 2-in-1 50MHz Digital Oscilloscope & DDS Signal Generator

Product Description

The FNIRSI DS215H Digital Oscilloscope & DDS Signal Generator is a compact 2-in-1 test instrument that combines a dual-channel digital oscilloscope with a built-in function signal generator. Designed for electronics testing, circuit troubleshooting, maintenance, and development work, it provides two essential laboratory functions in a portable handheld device.

The oscilloscope features a 50MHz analog bandwidth and a maximum real-time sampling rate of 250MSa/s, allowing users to capture and examine electrical signals across two input channels. Its 8-bit vertical resolution, adjustable time base, and selectable voltage sensitivity support waveform observation and analysis across a range of electronic applications.

The DS215H offers a time base range from 20ns/div to 20s/div and vertical sensitivity from 10mV/div to 10V/div. It supports AC and DC input coupling, rising-edge and falling-edge triggering, and Auto, Normal, and Single trigger modes. Automatic measurement functions include frequency, period, peak-to-peak voltage, maximum and minimum values, average voltage, RMS, amplitude, duty cycle, and pulse width.

In addition to its oscilloscope functionality, the DS215H integrates a DDS function generator capable of producing 13 waveform types over a frequency range of 0–50kHz. Users can adjust output frequency, amplitude, and duty cycle, with a frequency adjustment step of 1Hz. This makes the instrument useful for generating test signals when evaluating amplifiers, filters, electronic circuits, and other signal-processing stages.

The instrument features a 3.5-inch IPS color display with a 480 × 320 resolution, providing a clear view of measured waveforms and operating parameters. It also supports waveform screenshot storage and viewing, helping users document measurements and review test results.

Powered by a built-in 1500mAh rechargeable lithium battery, the DS215H supports portable operation and USB Type-C charging at 5V/1A. Its compact design makes it suitable for electronics workshops, educational laboratories, field maintenance, and development benches where a full-size oscilloscope may not be practical.
