Three, module application:

1,Local oscillator;

2,Test equipment;

3, synchronous clock,High frequency signal source;

4, AD9959 learning module;

Four, module performance parameters:

1, control through the USB (5V power supply), the AD9958/AD9959 module uses +-5V power supply,Note: because of load imbalance with the positive and negative terminals, + - mode power supply can not, this may lead to the negative terminal of the voltage is too high;

2, using high-speed amplifier output coupling, impedance matching, 200M post filter;

3, the output frequency of 0---200M, 0.12HZ resolution;

4, the output range of 0 - 2VPP1M high resistance, 0--1VPP50 europe,

Amplitude flat: 0 - 100M 0.4dB

100M---150M1dBFlatness

Amplitude can be achieved through the upper computer software to achieve the 1024 level of fine adjustable;

5, independent phase adjustment, 0.022 degree fine phase resolution, IQ and other signal can be achieved.
