Setting your Scan Mode
The selected Scan Mode provides three different methods of specifying the channels
you wish to look at. These are Range Mode, Auto Mode, and List Mode:
Range Mode: All channels between the Start and Stop Freq/Channel are
displayed. The channels are separated by the Freq/Channel Step value. Metrics
are only computed for the single channel indicated by the vertical yellow line,
which can be adjusted by using the [Display], [Position] menu keys. For further
details, see “Setting the Display Position” on page 349.
If the channel you specified using the [Position] menu key can not be
demodulated, you will see the message “No valid Slot Sync found” displayed on
the graphic portion of the screen for all three views, and the numeric metrics at
the bottom of the screen will be dashed out. In the Power versus Time view, the
PvT Mask will not be shown even if you have switched it on.
