Description

DSO3D12 (3-in-1) 2-ch Oscilloscope (120 MHz) + Multimeter + Signal Generator

The DSO3D12 is a portable dual-channel oscilloscope featuring a high-definition 3.2″ display and a 120 MHz bandwidth, packed with powerful features.

It integrates a high-precision True RMS multimeter that supports rapid software calibration. When measuring low voltage, resistance, or continuity, both the oscilloscope and multimeter functions can be used simultaneously.

The built-in waveform generator can output various waveforms including sine, square, and triangle waves. The voltage amplitude is 2.5 V, the frequency is adjustable from 0 to 2 MHz, and the square wave duty cycle can be adjusted from 1% to 99%.

Using MCU and FPGA chips, the DSO3D12 ensures high-speed signal acquisition and fast data processing, providing a smooth user experience with a wealth of functions.

The DSO3D12 is widely used in various applications, including:

  • Basic R&D
  • Chip debugging
  • Car repair and maintenance
  • Home appliance repair
  • DIY debugging
  • Radio amateur activities
  • Switching power supplies
  • Frequency converters
  • Welding machines
  • Bus waveform analysis
  • Crystal waveform analysis

This versatility makes the DSO3D12 an invaluable tool for a wide range of technical and electronic tasks.
