or Query
1 byte Command or Query.
Sets or returns the Tx Scrambler state, where:
0 = Off
1 = OM-73 Scrambler
2 = V.35 Scrambler
3 = Modified V.35 (Comtech EF Data Closed Network)
4 = Reed-Solomon Synchronous Scrambler
5 = IBS Overhead Synchronous Scrambler
6 = TURBO Scrambler
Note: Depending on the active modem mode, FEC type, overhead
type, and RS state, not all selections will be valid.
Example: <0001/TSC=1{CR} (OM-73 Scrambler On)
5 bytes Command or Query.
Sets or returns the Tx Spreading Equation in the form abbbb, where:
a = 0 (for Equation 0) or 1 (for Equation 1)
bbbb = GSN (Gold Sequence Number) 0000-9999
(for Equation 0) OR GSN 0000-4095 (for Equation 1)
Example 1: <0001/TSE=05000{CR} (Tx Equation 0, GSN 5000)
Example 2: <0001/TSE=14095{CR} (Tx Equation 1, GSN 4095)
3 bytes Command or Query.
Sets or returns the Tx Spreading Factor in the fiorm xxx, where:
xxx = value from 1 to 512.
NOTE: Values other than 1 are only valid when Modem Type =
LDPC.
Example: <0001/TSF=001{CR} (Tx Spreading Off)
1 byte Command or Query.
Sets or returns the Tx Spectrum Invert selection in the form x, where:
0 = Normal,
1 = Tx Spectrum Inverted
Example: <0001/TSI=0{CR} (selects normal)
