  • Dual Independent Channels: CH1 and CH2 offer completely symmetrical channels, each independently configurable.
  • User-Defined Waveforms: Supports user-defined waveforms with a memory depth of 2048*12 bits and a sampling rate of 250MSa/s.
  • Burst Output Function: Features pulse trains burst output with three trigger modes for versatile applications.
  • Measurement Functions: Includes a 100MHz frequency meter and counter function.
  • Amplitude and Offset Adjustments: Signal output amplitude ranges from 10mVpp to 20Vpp, with a DC offset adjustment range of -10V to 10V.
  • Digital Signal Output: Offers a digital signal output function with a CMOS output range of 0~10V.
  • High Resolution: Waveform generator with up to 12 bits width, ensuring delicate output waveforms with low distortion.
  • CNC Functions: Full CNC functionality for displaying and adjusting current output signal parameters such as amplitude, offset, frequency, duty cycle, and phase difference.
  • Computer Connectivity: Connects to a computer for remote control, allowing users to edit and download arbitrary waveforms.
  • High Frequency Accuracy: Achieves frequency accuracy up to 10^(-6) magnitude with a total range frequency resolution of 10mHz.
  • Tracking Function: Built-in frequency, amplitude, offset, duty cycle, and waveform parameters follow function for easy use.
  • Scanning Features: Includes frequency linear sweep and logarithmic sweep functions with customizable start and end points.
  • Storage Capability: Can store up to 20 user-defined parameter sets for convenient recall.
  • User-Friendly Operation: Operates through key input with an LCD1602 display in English, allowing for direct digital setting or continuous adjustment via the knob.
  • Input Protection: Features input over-voltage protection with an extended power input range of AC85V to AC260V.
  • Output Protection: Equipped with output short-circuit protection, ensuring continued operation in load short-circuit situations for over 60 seconds.
