RF amplifier, remotely powered
6. If automatic upstream alignment is chosen, the the transmission loss of the
incoming cable span has to be estimated. To do so, enter the
previous
downstream level
and
previous downstream slope
.
7. You can automatically start the
ALSC after successful auto-alignment
.
8. Now you can
start the auto-alignment
process. In case of wrongly plugged
modules or severe level deviations there will be a notification.
