Step 6. Make the measurements now

This procedure describes how to initiate immediate testing. For information
on making measurements at a later time, refer to "Making Timed System
Measurements" later in this chapter.
is selected, system CTBKSO will be measured using the channel specified
using the SYS BTS TST CHNL softkey located in the Setup menu.
The default is channel 4. System CTB will be measured using the offset
specified by the CTB FREQ OFFSET softkey located in the Setup menu.
The default value is 6 MHz above the test channel's visual carrier. System
CSO will be measured using the offset specified by the CSO FREQ OFFSET
the test channel's visual carrier,
Alternatively, set the SYS BTS TST CHNL to the highest channel in
the system. If there are no signals just above the top channel, set the
CSO FREQ OFFSET to 7.25 MHz. These settings will measure the CTB
and + 1.25 MHz CSO beats in the clear just above the top channel. If
there are signals just above the top channel, such as digital music signals,
add increments of 6 MHz to the CTB and CSO offsets until a spot in the
clear is found. However, going too far into roll-off can compromise the
measurement results.
3. You can select whether results are to be printed (if you have a printer
connected to the analyzer), stored on a RAM card, or sent to the screen:
