2. Perform a wideband sweep:
a. Press
Preset then press Spec Anal to get the SPECTRUM
ANALYZER screen.
b. Set the RF Gen controls to Track, and the Port/Sweep field to
Dupl. This directs the tracking generator to the DUPLEX OUT
port.
c. Connect the DUPLEX OUT port to the ANT IN port.
d. Set the Main control to Ant.
e. Set the Center Freq to 501 MHz, and the Span to 1 GHz. You
should see a (roughly) flat line across the screen, varying about
4dB. “Generator sweep truncated” may appear, but does not
indicate a problem.
3. Run the Performance Tests associated with the repair as indicated in
Table 3-2 on page 75, or run all the tests in Chapter 8 , “Performance
Tests,” on page 173 to verify that the Test Set meets its overall
performance specifications.
