Description
Default Value
Frequency
This is the desired frequency of the
receiver in MHz.
1450.5 MHz, 1800.5 MHz, or
2370.5 MHz for Lower-L
band, Upper-L band, or S
band, respectively
1450.5 MHz for tri band
4675.0 MHz for C band
Modulation
This is the modulation method used.
Value of 0-10
Options are:
0 - PCM/FM
1- SOQPSK
2 - MHCPM
3 - BPSK
4 - QPSK
5 - AQPSK
6- AUQPSK
7 - OQPSK
8 - UQPSK
9 - DPM
11 - STC
12 - SOQPSK/LDPC
13 - STC/LDPC
QPSK, if it exists
If not, then PCM/FM
If not, then SOQPSK
If not, then MHCPM
Modulation Index
Tracking*
In PCM/FM mode only
Allows Trellis demodulator to
automatically detect and adjust to
Modulation Indices not at ideal 0.7
A (Acquire)
*Note:
If the user cannot guarantee that the transmit source is a new generation, digitally synthesized transmitter,
the receiver should be left in Tracking mode. Failure to do so will cause the receiver to fail to acquire improperly
deviated signals altogether. All tracking loops are already optimized for fastest synchronization, and should not be
adjusted in any way.
If the user knows for sure that the transmit source is digitally synthesized, the tracking should be set to Off, for the
minimum acquisition time.
