321.4 MHz IF Out Amplitude Test Procedure

1. Refer to the previous steps for the Option IF Output measurements, connect the PSA
rear panel 321.4 MHz IF Out to the RF Input of the test spectrum analyzer. Use an
SMA or APC 3.5 mm cable and appropriate adapters. Initialize the test spectrum
analyzer parameters as follows to measure the 321.4 MHz IF Out on the rear panel of
the PSA.

2. Record the amplitude of the 321.4 MHz Output. The signal level should be –12 dBm
(± 2 dB). This equates to a 2 dB loss between the RF Input and the 321.4 MHz Output
port.
NOTE For units with Option H7L or HNQ the signal level should be 2 dB lower.
