Figure 2-22. Calibrator Amplitude Accuracy Test Setup

11.Connect the equipment as shown in Figure 2-22. The EMC analyzer should be positioned so that the setup of the adapters, LPF and attenuator do not bind. It may be necessary to support the center of gravity of the devices.

12.On the power meter, press the dBm mode key. Record the Power Meter Reading in dBm in the worksheet as the Power Meter Reading.

13.Subtract the Corrected Insertion Loss (step 10) from the Power Meter Reading (step 12).

CAL OUT Power = Power Meter Reading 0 Corrected Insertion Loss

Example: If the Corrected Insertion Loss is 010.0 dB, and the power meter reading is 030 dB, then (030 dB) 0 (010.0 dB) = 020 dB

14.Record this value as TR Entry 1 of the performance verication test record as the CAL OUT power. The CAL OUT should be 020 dBm 60.4 dB.
