FNIRSI DS215H Oscilloscope

FNIRSI DS215H Oscilloscope

The FNIRSI DS215H is a compact dual-channel digital oscilloscope featuring a 50 MHz bandwidth and an integrated function generator. Designed for electronics professionals, it enables both signal analysis and generation in a single device, suitable for maintenance, R&D, testing, and diagnostics in workshops and field environments.

High Measurement Accuracy and Fast Sampling

Utilizing a modern architecture based on FPGA, MCU, and ADC chips, the oscilloscope delivers high performance and operational stability. It offers an analog bandwidth of 50 MHz and real-time sampling rates up to 250 MSa/s, allowing precise signal analysis across diverse applications. The high measurement resolution facilitates detailed waveform observation and detection of short-duration signal changes.

Function Generator with Extensive Configuration Options

The built-in function generator supports 13 waveform types, expanding testing and design capabilities. It operates over a frequency range of 0 to 50 kHz adjustable in 1 Hz increments, with adjustable frequency, amplitude (0.1 V to 3.0 V), and duty cycle (0–100%), suitable for both simple and advanced laboratory tasks.

Convenient Operation

The 3.5-inch color IPS display with 480 × 320 pixel resolution provides clear waveform visualization and an easy-to-read interface. Intuitive control via a rotary knob and buttons enables quick setting adjustments and access to context-sensitive menus. The device supports screenshot capture and review for result analysis and documentation.

Safe Operation Even at High Voltages

Designed for demanding conditions, the oscilloscope supports peak input voltages up to ±400 V and includes high-voltage protection features. It offers selectable probe attenuation factors of 1X or 10X, adapting to measurement requirements. Compliance with GB/T 15289-2013 safety standards ensures reliable and safe operation.

Ready to Work Anywhere

Its compact dimensions (approx. 66 × 110 × 19.5 mm) and lightweight design (approx. 138 g) make it highly portable for field use. The built-in 1500 mAh lithium-ion battery provides up to 4 hours of continuous operation, rechargeable via USB-C (5 V / 1 A). This versatile tool is ideal for service technicians, electronics technicians, engineers, and professionals involved in electronic circuit design, diagnostics, and testing.
