PSA Functional Tests
Frequency Readout Accuracy

Procedure

1. Configure the equipment as shown in
alignment has been performed within the past 24 hours.
2. Perform the following steps to set up the equipment:
a. On the synthesized sweeper, press

b. On the spectrum analyzer, press
3. Set up the spectrum analyzer by pressing:

Span MHz
Ensure Ref Level is set to 0 dBm. In addition, ensure Resolution BW and
NOTE
Video BW are both set to Auto.
4. Press on the analyzer to measure the frequency readout accuracy. If the
Peak Search
instrument is functioning correctly, the marker reading in the active function block will
be between the values listed in
Frequency Readout column in
5. On the spectrum analyzer, change the span and center frequency as listed in
6. Change the synthesized sweeper frequency to match the center frequency of the
analyzer.
7. Repeat steps 4 through 6 until the Marker Frequency Readout column of
complete.
