Procedure

1. Zero and calibrate the power meter and power sensor as described in the
2. Configure the equipment as shown in
Connect the power splitter to the signal analyzer input using the
appropriate adapter. Do not use a cable. An adapter will only be necessary
if the PXA input connector is Type-N.
3. Assure the signal analyzer's built-in auto alignment has been performed
4. Press Mode, Spectrum Analyzer, Mode Preset on the signal analyzer, and
5. Set up the synthesized sweeper by pressing:
6. Set up the signal analyzer by pressing:
7. Adjust the synthesized sweeper output power for a power meter reading
8. On the signal analyzer, press Single.
9. Press the Peak Search key on the signal analyzer to position the marker on
