3.3.2.4 Signal Strength Offset Calculator
The signal strength offset calculator determines parameters needed to perform the signal strength
channel calibration (2.3.5.2) procedure. The user enters observed voltages from receiving equipment
and the required offset for both of the RC3000’s signal strength channels is calculated.
POLARITY:NEG SIG_OFFSET
ON_SAT: -3.223 SS1_OFF: -0.0655
OFF_SAT: 7.651 SS2_OFF: -0.5447 *
NOTE POLARITY & OFFSETS <MODE>EXIT
ON_SAT: ENTER ON SATELLITE VOLTS<-15.00/15.00>
Enter the voltage coming from the receiving equipment when “on satellite”.
OFF_SAT: ENTER OFF SATELLITE VOLTS<-15.00/15.00>
Enter the voltage coming from the receiving equipment when “off satellite”.
NOTE POLARITY & OFFSETS <MODE>EXIT
After the two voltages are entered, the required offset voltage is calculated for both signal strength
channels and the polarity (NEGitive or POSitive) is displayed. The channel that would be most
appropriate for the entered voltage characteristics is noted by a “*”.
Note that if the entered values are out of range or the two values are too close together to allow a
meaningful calculation the following message is displayed:
INVALID ENTRY <MODE>EXIT & TRY AGAIN
The screen may then be exited and reentered to start data entry again.
