SELECTIONS/DESCRIPTION
Edit the size, in bits of the Plesiochronous/Doppler
Buffer.
Values of +/- 256, 512, 1024, 2048 and 4096 bits
are possible. If the buffer is disabled, a warning
message will be displayed if this screen is entered.
SELECTIONS/DESCRIPTION
This should normally be in the OFF position. When
in the ON position, the receive spectrum is inverted
(which is the same as reversing the direction of
phase rotation in the demodulator). Note that in
BPSK mode, the demodulator will automatically
synchronize to either the normal time-ordering of
bits FEC codeword pairs, or the inverted ordering
used by certain other manufacturers.
SELECTIONS/DESCRIPTION
The range of values is from 2.0 to 16.0 dB. The user
may select a value here, and if the Eb/No falls
below this value, a receive traffic fault will be
generated.
