c. All Above Avg – the measured IRD Signal Quality of all transponders tested is
above the average limit and the measured Signal Level of all transponders is
above the Signal Level limit.
d. Some Below Avg – the measured IRD Signal Quality of at least one of the
transponders tested is below the average limit and the measured Signal Level of
all transponders is above the Signal Level limit.
If a lock is not obtained for a transponder, the IRD column will display “??” instead of the
measured signal quality value. The table will be filled in as the transponders are
measured in sequence. When all limit scan transponders have been scanned, the
individual transponder grades and the summary will appear on the screen.
The Limit Scan will continue running constantly until stopped by the user. You will receive
a summary at the bottom of the screen after each cycle of limit scanning has been
completed.
The following keys are active while scanning:
EDIT – lets you edit the transponder list and limits (see below)
SAVE – collects and stores a complete limit scan for later upload to a PC
LNB ON/OFF – also selects different LNBs in a multi-LNB system
EXIT - returns to the main Run screen
Left / Right Arrow keys – scroll between satellites (as in the Run Screen)
Editing Limits
If limits have not yet been defined, a message will be displayed that says “No limits for orbit”.
