CONTROL-1500A Single Axis Antenna Controller
found in step 2 (use the band specified at the end of the previous sentence).
If both controller AGC inputs are utilized, record similar values for 'RCV2 – on satellite –
strong band' ______ (C or Ku band) and 'RCV2 – off satellite – weak band' _____ (C or Ku
band). If both controller AGC inputs are utilized steps 7 through 9 must be performed for
each AGC channel. Use the Scroll Up/Down keys to view the AGC channel whose pots
are being adjusted.
7. Go to MANUAL mode, position the antenna 'RCVx - off satellite – weak band' (if it is not
already there), Adjust the OFFSET pot (for POSITIVE polarity receivers) or the GAIN pot
(for NEGATIVE polarity receivers) so that the signal strength reading is about 75.
If the AGC has POSITIVE polarity and the signal strength is too low, turn the OFFSET pot
counter-clockwise. If the AGC has POSITIVE polarity and the signal strength is too high,
turn the OFFSET pot clockwise.
If the AGC has NEGATIVE polarity and the signal strength is too low, turn the GAIN pot
counter-clockwise. If the AGC has NEGATIVE polarity and the signal strength is too high,
turn the GAIN pot clockwise.
8. While still in MANUAL mode, position the antenna 'RCVx - on satellite – strong band' and
adjust the GAIN pot (for POSITIVE polarity receivers) or the OFFSET pot (for NEGATIVE
polarity receivers) so that the signal strength value is about 650.
If the AGC has POSITIVE polarity and the signal strength is too low, adjust the GAIN pot
clockwise. If the AGC has POSITIVE polarity and the signal strength value is too high,
adjust the GAIN pot counter-clockwise.
If the AGC has NEGATIVE polarity and the signal strength is too low, adjust the OFFSET
pot clockwise. If the AGC has NEGATIVE polarity and the signal strength value is too high,
adjust the OFFSET pot counter-clockwise.
9. Position the antenna 'RCVx - off satellite – weak band'. If the signal strength is between 50
and 100, proceed to step 11. If the signal strength is less than 50 or greater than 100
perform steps 8 and 9 again.

Programming Geostationary Satellites
After the limits have been set and the slow speed code determined, geostationary satellites
can be programmed into the controller's memory.
All satellites are programmed into memory via Setup (SET) mode. In Setup mode the user can
jog the antenna in azimuth and elevation to peak up on a satellite, specify the satellite name,
and jog the polarization to assign H (horizontal) and V (vertical) polarization values. This
information is retained in the controller's non-volatile memory. After a satellite has been stored
in the controller's non-volatile memory via Setup mode, the user can automatically position the
antenna the satellite by invoking the controller's Auto (AUT) mode. In Auto mode, the Scroll
Up/Down keys are used to select a satellite. When the Enter key is depressed the controller
will move to the selected satellite.
