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 P ower Meter
Reading in dBm in the worksheet as the P ower Meter Reading.
13. Subtract the Corrected Insertion Loss (step 10) from the P ower Meter
Reading (step 12).
CAL OUT P ower = P ower 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 .
