Max ES/NO
The Satellite peaking routine will stop at the set value of the SNR signal thus reducing
the peaking time after reaching the highest set value. Modifying and or misconfiguring
this parameter may inhibit satellite searching sequence and stop the peaking before
reaching the highest possible signal. Only change this value if the highest Maximum
ES/NO value is known to the user otherwise leave at default value of 255 to ensure
peaking is performed at the highest signal. This field is grayed out when Reference
Satellite is enabled and default value set to 255.

LNB_LO and Tone section
LNB_LO
This drop down menu allows the user to change the LNB frequency settings to relock
back onto satellite signal. The Normal operation setting is 10.75 and the controller
default setting will reflect this; users should use the default setting at all times with
carriers from table list or a carrier can be manually entered. If required to change LNB
LO, than DVB frequency will also change as per the following equation: DVB tuner==IF
fre (10.75-LO), where LO = the selected LO from the menu, IF Frequency is the
selected/entered Frequency from menu (or Satparam database table).
0 – 10.75
1 – 9.75
2 – 10.00
5 – 10.60
4 – 11.30
Note:
Values 0-4 represent controller side value settings.
