Description
Unit DDS is a signal source Unit. It uses the AD9833 programmable waveform generator + STM32F0 control scheme. It provides an I2C communication interface (addr: 0x31) and operates by configuring registers in practical use. It allows easy control of the signal source to output various waveforms (sine wave, triangle wave, square wave output, sawtooth wave, signal output amplitude 0-0.6V), and to adjust frequency and phase. It also supports sleep strategies to further reduce power consumption when idle. This Unit is suitable for use as a signal source in the electronic circuit prototyping of various test instruments.
