Appendix E E–3 MN-SLM-5650B
• 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)
