RC2000C Polar Tracking Antenna Controller
5.10.8
Time and Date Settings
Access to the Time and Date CONFIG mode items is permitted only when the Expert Access flag is set.
ENTER TIME (HH.MM.SS): 08.46.00
USE 0-9 OR .
The real-time clock must be set to establish a time reference for all tracking data stored in the controller.
Enter the local time using the 0-9 keys and the . key to separate the hours, minutes, and seconds fields.
Each field must have two digits entered; i.e., 8 must be entered as 08 or the unit will not accept the entry.
The time cannot be changed for daylight-savings time purposes once valid track data is stored, or the unit
will not function properly.
ENTER DATE (MM.DD.YY):07.03.92
USE 0-9 OR .
Enter the current data in the format shown. Again, use the 0-9 keys to enter the month, day, and year
fields, and use the . key to separate fields. Single digit fields must be entered with a 0 preceding, as
shown in the example for 07.03.92.
5.10.9
Signal Strength Parameters
The controller has to have signal strength information for tracking inclined orbit satellites. Signal strength
information is generally obtained from the receiver's automatic gain control (AGC) system. The
procedures used to adjust the controller's AGC input circuits and obtain these parameters is described in
section 4.4.1 - AGC Adjustment and Configuration. Access to these CONFIG mode items is permitted
only when the Expert Access Flag is set.
AGC POLARITY FLAG;1
0-NEGATIVE 1-POSITIVE
The AGC Polarity Flag tells the controller what the sense is on the input AGC voltage used for tracking.
A positive sense is defined as one that increases in magnitude as the RF signal strength increases. If the
AGC voltage decreases as the RF signal increases, its sense is considered negative. Enter the
appropriate value, either 0 or 1, followed by ENTER to key in the value.
AGC C BAND THRESHOLD:125
0 - 999
When the receiver is tuned to a C band satellite and the signal strength is above the AGC C Band
Threshold value, it is assumed that a satellite signal is present. The same threshold is applied to both
AGC channels.
AGC K/L BAND THRESHOLD:150
0 - 999
This is similar to the C band threshold described above, except it pertains to Ku or L band. If the signal
strength is above the AGC K/L Band Threshold value when the receiver is tuned to a Ku or L band
satellite, the controller assumes that a satellite signal is present.
5.10.10
Antenna Parameters
The following items specify antenna related parameters which are used by the tracking system. Access
to these items is only permitted when the Expert Access flag is set.
