The output frequency of TI lmx2595evm does not correspond to the set frequency in TICS PRO.At present, both board connection methods have been tried as shown in figure. I have Click the interface in USB communications, and the green board indicator will flash. The output end is connected with a spectrum analyzer

, my operation process is to connect the device on tics pro, click default mode in the default configuration, output port a should output 7GHz spectrum, but the output is 4GHz
The default configuration of the software used is shown in the figure below. The screenshot is taken after test. The device is successfully connected during the test

。I have tried to click write all register in raw registers and write all register in USB communications. The effect remains the same.
Is my device connected in the wrong way or the operation process wrong?
Please give me some advice! Thank you very much!
