FNIRSI DS215H 2-in-1 Dual Channel Digital Oscilloscope & DDS Signal Generator – 50MHz Bandwidth, 250MS/s Sampling Rate, Portable High-Precision Electronics Testing Instrument

The FNIRSI DS215H is a next-generation 2-in-1 electronics testing powerhouse designed for engineers, technicians, educators, and electronics enthusiasts who demand precision, versatility, and portability. Combining a dual-channel 50MHz digital oscilloscope with a high-performance DDS (Direct Digital Synthesis) signal generator, this device offers unmatched convenience for waveform measurement, signal generation, and circuit diagnostics in one compact handheld unit.

Unmatched Dual Functionality

• 50MHz Digital Oscilloscope – Delivers 250MS/s real-time sampling rate with deep waveform capture capability, ensuring accurate representation of even the fastest transient signals.

• DDS Signal Generator – Outputs multiple waveform types including sine, square, triangle, ramp, pulse, and custom patterns, making it perfect for testing, simulation, and calibration.

Precision Engineering for Professionals

The DS215H’s oscilloscope mode is equipped with two fully independent input channels, allowing simultaneous monitoring and comparison of different signals. The high-accuracy DDS generator produces stable, low-distortion waveforms, making it ideal for analog and digital circuit testing.

Its advanced triggering options (edge, pulse, video) ensure stable waveform capture even in complex electronic environments, while the high signal-to-noise ratio guarantees clear visibility of low-amplitude signals.

Portable Lab in Your Hand

Weighing just a fraction of traditional benchtop equipment, the DS215H is lightweight and battery-powered, enabling field service engineers, mobile technicians, and educators to carry a complete signal analysis and generation solution anywhere. The bright TFT color display ensures excellent waveform visibility indoors or outdoors, and the intuitive menu system means even beginners can operate it with minimal learning curve.
