Can I use the PSM-4900 to help align the station antenna? Is an AGC output provided to feed to automatic antenna positioning equipment?

Yes – The PSM-4900 has a single analog output that is produced by the main processor and converted to analog by a D/A converter. The parameter selected for this output can be either the AGC, Eb/No or Mod CXR Level selected in the . The slope and polarity are selected using the “Zero†and “Full†parameters below this. The signal is available at the rear panel on the J5 Alarm Connector, pin 5 with the Ground return on pin 6. See Installation section 2.3.3, “Alarm Connectionâ€, and Operations section 3.11 for more information on connection and use of the monitor function. The AGC has been the classic parameter used for this type of function, but the PSM-4900 provides an output that may be better in most situations. That is the Eb/No, which is a function without the slope changes and negative signal sense of the AGC signal.
