Description
1Hz-100KHz PWM Function Generator DDS Function Signal Generator Module
Overview
HM350 is a small signal generator, the maximum can produce 100KHz frequency, duty cycle adjustable pulse signal; produce servo control signal; measurement frequency; The module is simple to use, and by pressing the key operation to input the frequency data, the output frequency is updated immediately.
product application
signal generator; instrument calibration; DC motor control; Measurement frequency;
