
Connect the Coupler, Low PIM Load and Spectrum Analyzer to the PIM-P
Analyzer (use torque wrench)

Set Spectrum Analyzer to proper measurement range

Set the PIM-P to Analyzer Mode

Set the frequencies of carrier signals 1 and 2 to the start and end frequency of the
provided frequency band.

Set the power level of each signal to 40 dBm (10W) – with ALC: ON

Switch RF Power ON

Spectrum analyzer should show both PIM-P frequencies with +/-100 kHz accuracy.
If the reading deviates, switch RF power OFF, disconnect connections, reconnect and
repeat the test.
If the reading is off by more than 200 kHz, it may be an indication that the
synthesizer module is malfunctioning. In this case, contact your nearest AWT Service
Center.
With the reading in limits, continue procedure:

Increase on F1 Signal frequency by 1MHz

Measure both frequencies

Repeat the process you are no longer able to increase the signal frequency F1

If done, set F1 back to start frequency

Decrease F2 by 1 MHz

Measure both frequencies

Repeat the process you are no longer able to decrease the signal frequency F2
 Switch “RF Power OFF
Rx Power and Receiving Frequency 12.3.3
The following measurements have to be executed with utmost care:
If too much power is applied to the PIM-P Analyzer, the receiver module will be
damaged.
If the RF output power of the PIM-P is accidentally switched ON, it will damage
the Signal Generator.
In order to measure the accuracy and frequency selectivity of the receiver, the
following components and
