Procedure
This performance test consists of two parts:
Part 1: Third Order Intermodulation Distortion
Part 2: Second Harmonic Distortion
Perform Part 1 before Part 2.
Part 1: Third Order Intermodulation Distortion
1. Zero and calibrate the power meter and microwave power sensor in
log mode (power reads out in dBm), as described in the power meter
operation manual.
2. Connect the equipment as shown in Figure 2-49 using the 300 MHz
low pass filter with the output of the directional bridge connected to
the power sensor.
