cl.lead x seconds Cross-level commands are issued
cl.lead seconds ahead of the
actual position.
az.park x degrees Azimuth park or stow position.
-400.00=Do not stow.
el.park x degrees Elevation park or stow position.
-400.00=Do not stow.
min.track.el x degrees Minimum tracking elevation. No
tracking occurs below this
elevation.
Note : min.track.el -
(abs) el.orient must not be less
than 0.0.
threshold x dBM
(negative) or
counts
(positive) Used by autoalign to determine
signal lock.
counts.deg x counts Receiver signal change per
degree of elevation change. Not
used on conscan antennas.
search.delay x seconds Delay before beginning search
mode when the antenna’s signal
strength is below the threshold.
See
constants on next page.
search.stepperdeg x steps Conversion of degrees to antenna
step counts. Used to convert
degrees to step increments for
conscan motions or for searching.
[45.5111] (There are 45.5111 steps
per degree). Do not change this
value.
search.limit x degrees Maximum box size used in search
mode.
search.step x degrees Box step size while searching.
back.azoffset x degrees Azimuth offset in determining
background noise level.
back.eloffset x degrees Elevation offset in determining
background noise level.
back.nullzone x degrees Zone around the pass starting
position in which not to take
noise readings.
