1. Zero and calibrate the power meter.
2. Set the calibration factor on the power meter to the average value of the power sensor
between 50 MHz and 20 GHz (40 GHz for 8722ET/ES).
For example, if the power sensor calibration factor is 100% at 50 MHz and 92% at
20 GHz (40 GHz for 8722ET/ES), set the calibration factor to 96%.
3. Connect the equipment as shown in
