Scanning
Selecting “Limit Scan” from the Main Menu will start the Limit Scan screen. If limits have already
been defined for the presently selected satellite, the scanning will start immediately. The Limit
Scan is only useful if the LNB is being powered by the meter. Press the LNB soft-key (located
near middle right area of screen) to power the LNB. On a multi-LNBF setup, press the LNB soft-
key more than once to toggle from LNB1 to LNB2 to LNB3, etc. The satellite orbital position (i.e.
110.0W) related to each selected LNB port will be displayed in the top right corner of the LCD
screen.
For each transponder to scan, the screen shows:
1) Tr – The transponder numbers to be scanned (transponders must be defined by user)
2) dBm – The measured signal level value corresponding to each specified transponder (will
either be displayed in dBm, dBmV, or dBµV, depending on your chosen signal level
values in the Options menu)
3) IRD – The measured IRD signal quality value corresponding to each specified
transponder
4) A transponder grade next to each individual transponder:
a. FAIL - Below the minimum Signal Level limit or below the minimum IRD Signal
Quality limits
b. Low - At or above the minimum Signal Level limit and at or above the minimum
Signal Quality limits but below the average Signal Quality limits
c. Good - At or above the minimum Signal Level limit and at or above the average
Signal Quality limits
5) Summary of Limit Scan results - At the bottom of the screen, the user will see a
comparison to the minimum first (top row at bottom of screen) and the comparison to the
average second (bottom row at bottom of screen). Possible Limit Scan summary
messages that could be displayed at bottom of screen:
a. All Above Min – the measured IRD Signal Quality and Signal Level of all
transponders tested are above the minimum limits
b. Some Below Min – the measured IRD Signal Quality or Signal Level of at least
one of the transponders tested is below the minimum limit
