AD9959 module DDS module 4 channel signal source STM32 control to support the original official software

500Mhz AD9959 4 channel DDS module

Module features:

1, AD9959 module is senior engineer tries their best to build, PCB has the advantages of beautiful appearance, reasonable layout and design, pay attention to the use of materials, nano electronic pursuit is in the details.

2, AD9959 module all the control IO external, suitable for the needs of the complete function of the customer, for the two development, and do not have to pay attention to the design of the AD9959 module; in addition to our?Function evaluation board has been able to achieve most of the functions, has been able to meet the requirements of the majority of customers.

3, compatible with the ADI original PC software most functions, can achieve most of the AD9959 chip function, can quickly understand the characteristics of AD9959; the main functions are:A, automatic linear frequency / phase / amplitude scanning function; B, 16 kinds of frequency, phase and amplitude modulation mode; C, single frequency mode, support frequency, phase, amplitude adjustable;C, with the parameters of the save function (the official version does not have this feature);

4, to provide a Demo based STM32 program, you can quickly complete the simple control of AD9959. Simple IO operation, very easy to transplant to any control chip;

5, function evaluation board using USB interface, can be directly used USB power supply, easy to use;

6, AD9959 chip function introduction:

Four, module performance parameters:

1, evaluation board (with 5V - 5V power module) and AD9959 module is - 5V power supply can be directly through the USB (5V supply) or by behind the power supply method to assess the board with AD9959 module independent 5V power supply (if the operating frequency is relatively high, it is recommended).

2, the output frequency of 0---200M, the resolution is 0.12HZ or above;

3, the output range of 0 - 1VPP (1M high resistance), the amplitude will decrease with the frequency, the amplitude of the resolution is 1024.

4, independent phase adjustment, IQ and other signal can be achieved. Phase resolution: 0.022 degrees.
