Main Feature:

1. Produce a rich function waveform, can produce sine waves, duty cycle 1% to 99% square wave, triangle wave and two sawtooth.
2. Dual-channel reverse, and the duty cycle of CNC adjustable TTL output for easy debugging IGBT module.
3. All feature enables digital control, providing communication protocol can connect a PC to control.
4. Amplitude using potentiometers and NC combination, which can achieve full-scale output of CNC's 256 control.
5. External frequency measurement functions has a wide range, from 1Hz to 60MHz.
