Description
AD9833 Module Triangle Wave Sine Wave Signal Source Square Wave DDS Function Signal Generator Module
Product Description
AD9833 is a low-power, programmable waveform generator that can generate sine wave, arbitrary angle wave and square wave output Various types of detection, actuation, and time domain reflectometry (TDR) applications require waveform generators. The output frequency and phase can be programmed through software, which is easy to adjust. No external components are required. The frequency register is 28 bits; the clock rate is 25 MHz, and a resolution of 0.1 Hz can be achieved. Similarly, when the clock rate is 1MHz, the AD9833 can achieve a resolution of 0.004 Hz.

Installation Instructions
Precautions
(1) The module is a low-power module, and the power supply does not exceed 5.5V. (2) Since the module is a high-precision device, in order to avoid unnecessary interference, it is recommended to use a linear power supply. (3) For output signal, it is recommended to use SMA to BNC cable to observe the effect directly with oscilloscope. Poor contact or inferior cable may cause signal attenuation or excessive noise. (4) The delivered code is only for the supporting main control board, no MCU tutorial is provided, and additional functions need to be developed by yourself. (5) If you need to simply test the function of the module, it is recommended to use it with the control panel of our store. First, power the DDS module, and then power the control panel to generate a waveform. Long press the middle button to switch the function.
