1, DDS module can digitally generate signals with various frequencies and waveforms, which can be used for testing, calibration and research purposes.

2.DDS can synthesize the output signal of specific frequency by adjusting the step value of phase accumulator, which makes DDS very useful in generating accurate frequency modulation, frequency hopping and spectrum scanning.

3.DDS can generate various waveforms, such as sine wave, square wave and sawtooth wave, which is very important for testing equipment performance and verifying algorithms.
