OUTPUT TO OUTPUT ISOLATION

CDCE62002

Measurement Method

1.

Connect output 1 to the phase noise and Spectrum analyzer.

2.

Measure spurious on Outputs 1.

3.

Enable aggressor channel 0

4.

Measure spurious on Output 1

5.

The difference between the spurious levels of Outputs 1 before and after enabling the aggressor channel determine the output-to-output

isolation performance recorded.
