Operand 5 – F
T
= TRANSEC Framing Factor, where:
o
F
T
= N*16/[N*16+3], where ‘N’ is the selected Frame Length in AES blocks per
frame, in the range of 1 to 16.
o
F
T
= 1 if the TRANSEC encryption is disabled .
If the Direct Sequence Spread Spectrum (DSSS) feature is
enabled, then the simple equation for Chip Rate (
S
C
) equivalent
to (
B
w
) of the spread signal is: “
S
C
=K*S
R
”
where ‘
K
’ is the
programmed spreading factor (e.g. 2, 4, 8, 16, 32, 64, up to
512)
