Wideband Sweep
NOTE
Test Sets with firmware revision A.04.5X and above operate only at RF frequencies from
800 to 1000 MHz and 1700 to 2000 MHz. A text only error message "Input value
out of range" , will be displayed if invalid frequencies are set.
NOTE
This functional performance test requires the spectrum analyzer option in the
Test Set.
Wideband sweep configures the Test Set to test all of its major functions. A
problem located in the RF source or RF analyzer paths will become evident. In
this configuration, the spectrum analyzer and tracking generator will be used
to test and view the RF level and flatness of the RF source and RF analyzer
over a 1 GHz span.
1. Begin by using the same setup as analog loopback (Recall "SINAD"
2. Connect a short RF cable between the RF IN/OUT port and the ANTENNA
3. Configure the instrument for wideband sweep mode.

screen set the following fields:
• Set the Ref Level field to 0 dBm
• Set the Span field to 1 GHz (FW rev A.02.XX and below)

3b. On the SPECTRUM ANALYZER / RF Gen screen, set the following
fields:
• Set the Controls field to RF Gen Track
• Set the Port/Sweep field to RF Out
• Continuous across the display with no RF level dropouts
• Fairly flat, about 4 to 5 dB difference between end points
