DDS820 multiple signal generators
I. Overview:
DDS820 is a small variety of signal generators, which can also measure frequencies from 1HZ to 60MHZ. It can generate a sine wave signal of up to 8MHz. It can also generate triangle wave, increasing wave, decreasing wave, rectangular wave and one TTL pulse output.
This module is easy to use and input frequency data through key operation.
Product application:
● signal generator;
● Instrument calibration;
● DC motor control;
● Frequency meter;
