Fnirsi DS215H Oscilloscope

FNIRSI DS215H Oscilloscope
Working with electronics requires equipment that can keep up with even the most demanding tasks. The FNIRSI DS215H combines a dual-channel digital oscilloscope with a 50 MHz bandwidth and a function generator into a single, compact design, allowing you to both analyze and generate signals without the need for multiple separate devices. High measurement precision, intuitive operation, and a clear IPS display make it ideal for equipment maintenance, research and development, testing, and diagnostics in the workshop and in the field.


High Measurement Accuracy and Fast Sampling
The oscilloscope utilizes a modern architecture based on FPGA, MCU, and ADC chips, ensuring high performance and operational stability. An analog bandwidth of 50 MHz and real-time sampling at up to 250 MSa/s enable precise signal analysis in a wide range of applications. Thanks to its high measurement resolution, the device allows for precise observation of waveforms and detection of even short-duration signal changes.


Function Generator with Extensive Configuration Options
The FNIRSI DS215H is equipped with a function generator supporting 13 waveform types, which significantly expands the device’s capabilities during the testing and design of electronic circuits. The frequency range from 0 to 50 kHz, adjustable in 1 Hz increments, allows you to very precisely tailor the signal parameters to a specific application. You can freely adjust the frequency, amplitude, and duty cycle, making the generator suitable for both simple tests and more advanced laboratory work.


Convenient Operation
The 3.5-inch color IPS display with a resolution of 480 × 320 pixels provides a clear view of waveforms and an easy-to-read interface. Intuitive control via a rotary knob and buttons allows you to quickly change settings and access context-sensitive menus without having to search through options unnecessarily. An additional convenience is the ability to take screenshots and view them later, which facilitates the analysis of results and the documentation of measurements.


Safe operation even at high voltages
The device is designed for safe operation in demanding conditions. It supports a peak input voltage of up to ±400 V and is equipped with high-voltage protection features that enhance safety during measurements. The option to select a probe factor of 1X or 10X allows you to tailor the configuration to the nature of the measurements being performed. The device meets the requirements of the GB/T 15289-2013 standard, confirming compliance with applicable safety standards. Ready to Work Anywhere
Its compact and lightweight design means the FNIRSI DS215H fits easily into a service bag or backpack, making it ideal for field work. The built-in 1500 mAh lithium-ion battery provides up to 4 hours of continuous operation on a single charge, and powering via the USB-C port (5 V / 1 A) allows you to conveniently recharge the device almost anywhere. This versatile tool is designed for service technicians, electronics technicians, engineers, and professionals involved in the design, diagnostics, and testing of electronic circuits.
