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 RF 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 2-47 with the output of 
the directional bridge connected to the power sensor.
