Option IF Output Amplitude Test Procedure

This test verifies that the Option IF Output meets its amplitude accuracy specification. In
this test, the source is connected to the RF Input and a spectrum analyzer is connected to
the Option H70 Output.
Follow the steps below to prepare for the amplitude verification of the
Option IF Output on the rear of the PSA.
1. Preset the PSA DUT and all the test equipment.
2. Run Align All Now on the PSA. Press: [System] > Alignments < Align All Now.
3. Initialize the test equipment parameters as follows:

4. Zero and calibrate the power sensor.
5. Connect the power sensor/power meter to the end of the Type-N cable that is connected
to the source. Use an N (f) to N (f) adapter between the power sensor and the cable.
6. Adjust the source amplitude for a power meter reading of –10 dBm.
7. Disconnect the power senor from the cable and connect the cable to the PSA RF Input.
NOTE If the PSA has Option BAB (APC 3.5 mm input connector) an APC 3.5 mm (f)
to N (f) adapter is required between the PSA and the Type-N cable.
