Once you have selected your FEC use the down cursor
key to move on to Polarity.
The following LNB supply voltages can be selected.
V 13 Volts (Vertical or Right Hand Circular)
H 18 Volts (Horizontal or Left Hand Circular)
0 Volts (no voltage applied)
The zero volts option can be used where DC is already
supplied (by a power inserter) or where a splitter is used.
Once the Polarity has been selected use the down cursor
key to select the next option IQ Swap.
The IQ Swap function is not used very often; usually it
is set to
Normal
, however it is quite common to use IQ
Swap on C-Band services.
Tip:
Should you fail to acquire a lock once you have set
all the parameters try IQ Swap.
Once a lock is acquired found will appear and
the Q (Pre-BER) diplay will also appear. You
can save your custom carrier by pressing the
Save
button.
