AD9850 AD9851 module DDS module DDS signal generator module 40M sweep frequency PC control

Description
Signal generator =STC89C54RD+ +AD9850+LCD
Main functional characteristics:
* step value 0.01HZ
* sweep function: initial frequency, cut-off frequency, sweep time and sweep frequency step value.
* with PC communication function, the DDS signal generator can be controlled by upper computer software, making it more convenient to operate.
PC software does not need to be installed. It is compact, practical and convenient. It also provides PC software source code to facilitate your two change.
* the module outputs 2 sinusoidal and 2 square waves at the same time.
AD9850:0-40MHz minimum step value 0.029HZ
AD9851:0-70MHz minimum step value 0.029HZ
After 30-40MHz, the harmonics become larger and larger, and the waveforms will become more and more unclean.
Fang Bo: 0-30MHz does not distort
* use 70MHz's low pass filter to make the SN ratio of waveform better.
* parallel port and serial port data input can be selected through a jump cap.
* you can adjust the fine tuning potentiometer to get different duty cycles Fang Bo.
* AD9850 module adopts 125MHz active crystal oscillator, AD9851 module adopts 30MHZ active crystal oscillator.
Main differences between AD9850 and AD9851
* AD9850 has the highest clock frequency of 125MHz, and AD9851 has the highest clock frequency of 180MHz. The highest output frequency of AD9851 is higher than that of AD9850.
* AD9850 has no 6 frequency doubling, AD9851 has
* can be used for household appliances maintenance, audio test signal source, electronic hobby learners, MCU learning and so on.
