4. Adjust the synthesized signal generator amplitude to place the peak
of the signal at the reference level.
5. Set the spectrum analyzer control as follows:

delta amplitude reading in the performance verification test record
as TR Entry 1.
Part 2: Third Order Intermodulation Distortion
1. Zero and calibrate the measuring receiver and 100 kHz to 1500 MHz
power sensor in log mode (power reads out in dBm), as described in
the measuring receiver operation manual. Enter the power sensor’s
50 MHz Cal Factor into the measuring receiver.
75
Ω
Input only: Use a 75
Ω
power sensor.
2. Connect the equipment as shown in
Figure 9-16
using the 50 MHz
low pass filter and with the output of the directional bridge
connected to the power sensor.
75
Ω
Input only: Use the power sensor with a 50
Ω
to 75
Ω
mechanical
adapter in place of the 50
Ω
adapter.
The power measured at the output of the 50
Ω
directional bridge by
the 75
Ω
power sensor is the equivalent power “seen” by the 75
Ω
analyzer.
