OUTPUT TO OUTPUT ISOLATION
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.
