FNIRSI DST-201 Portable Digital Oscilloscope with DMM & DDS Signal Generator

The FNIRSI DST-201 is a compact and multifunctional handheld oscilloscope designed for both hobbyists and professionals. Combining a 1 MHz bandwidth oscilloscope, full-featured digital multimeter (DMM), and a 10 kHz DDS signal generator into one portable unit, the DST201 is a versatile diagnostic tool ideal for fieldwork, education, and electronics troubleshooting. Its built-in battery, color IPS display, and intuitive interface make it a reliable companion for on-the-go diagnostics.

Product Features:

  • 3-in-1 Functionality: Combines oscilloscope, digital multimeter, and function generator in a single device.
  • 1 MHz Bandwidth Oscilloscope: 5 MSa/s sample rate, 10 mV/div sensitivity, and real-time waveform capture modes (Auto, Normal, Single).
  • Wide Timebase: Adjustable from 500 ns/div to 20 s/div for detailed observation of both fast and slow signals.
  • Built-in DDS Generator: Outputs 13 standard waveforms up to 10 kHz, including sine, square, triangle, noise, half-wave, and more.
  • 2.8” IPS Display: Crisp 320x240 resolution with rich color contrast and wide viewing angles.
  • Rechargeable Battery: 3000 mAh battery offers up to 4 hours of continuous operation.
  • Auto Setup Function: Automatically configures parameters for periodic signals to simplify measurements.
  • Integrated Digital Multimeter: Measures AC/DC voltage, current, resistance, capacitance, frequency, temperature, and continuity.
