Choice
"No", "Yes"
If set to yes then coarse peaking will be skipped if the
modem transmitter is enabled.

fails.
These “Modem specific parameters” are considered common to several types of Modems and are
included in the standard set of parameters to avoid issue with duplication in multiple Software
Modules. If no Modem module is present, then these parameter values have no influence on the
behavior of the AAQ and the AvL antenna system.
Modem Minimum Wait Time – During acquisition, the controller will wait this amount of seconds
before attempting to read the modem signal level.
Modem Maximum Wait Time – If the AAQ controller has acquired but modem has not acquired and
wait time has been exceeded, the controller will then proceed to the secondary, then tertiary
acquisition method. Should these also fail to acquire, the controller will present the user with the
message, “Acquisition Failed, all signal sources tried”.
The Line Scan parameters establish the overall height and number of lines used in the standard
Acquisition raster scan. Elevation Step Size should be set as large as possible, while at the same time
insuring that a satellite located midway in between the lines is easily detected. The number of Max
Elevation Steps should be selected to set a reasonable overall height for the raster scan. Typical number
of 3 is used for default.
