4. Check the relevant calibration lines in accordance with the LNB bands (single, dual or
quad). The lines are ordered by LNB bands according to the LNB voltage/tones and by
NBR IfBw (50KHz, 150KHz and 300KHz).
NOTE:
Calibrating an excess number of lines (for example, all lines for a single-band LNB) will
result in the measurement time increasing, but does not affect the system adversely. Any
extraneous information is ignored.
