PARAM*
Scan Offset The scan offset is to offset the angle difference
between the black marker on the sub-reflector and the
optical sensor.
Track Scale The track scale is to control the tracking speed while
the antenna is tracking the satellite.
Detect Level The detect level is to set the satellite signal detection
level.
WRS Level The WRS level is to set the WRS (Wide Range Search)
detection level.
Track Offset The tracking offset is to offset the satellite signal
tracking level.
Power Level The power level is to distinguish the voltage between 13 V
and 18 V.
DiSEqC The DiSEqC level is to distinguish 0KHz tone and
Level 22KHz tone.
Offset RH-LH The offset RH-LH is to offset the signal difference
between RHCP and LHCP.
EL Offset The EL offset is to offset the angle difference
between the mechanical elevation angle and actual
elevation angle.
Use WRS Use WRS is to determine whether the system uses
WRS (Wide Range Search) level or not. "Use WRS"
and "WRS Level" are pair functions.
Offset Offset difference is to determine whether the system
Difference uses "Offset RH-LH" or not. "Offset Difference" and
"Offset RH-LH" are pair functions.
