NOTE: The frequencies of the Block Upconverter (BUC) and LNB must be entered first under the
‘System/General’ menu. The LB/ST will then calculate the Mod and Demod IF/RF frequencies.
Tx RF
This Frequency is precalculated by the LB/ST after the operator has
entered the frequencies of the BUC and LNB under the System/General
menu.
Tx IF
Enter in 1 MHz steps from 950-1525 MHz
Spectrum Inv
Inverts the direction of rotation for PSK modulation in demod.
Normal meets the IESS specification
Demodulation
Sets Demodulation type QPSK, BPSK, OQPSK
Swp Bound
Sets acquisition range for the demodulator
Input Limit
