Tx Spectrum TSI= 1 byte, 0 or 1
Invert
Tx Scrambler TSC= 1 byte, 0 thru 2

Description of Arguments
Command or Query.
Sets or returns Tx Sub-Mux Ratio (IP/Synchronous Interface) in the form xx, where
00=1/9 09=3/7
01=1/8 10=1/2
02=1/7 11=3/5
03=1/6 12=2/3
04=1/5 13=3/4
05=1/4 14=4/5
06=2/7 15=1/1
07=1/3 16=5/4
08=2/5 17=4/3
EXAMPLE: <0/TMR=01 (Selects ratio 1/8)
Command or Query.
Sets or returns Tx RS encoding in the form x, where:
0=Normal (based on the Open Network framing selected)
1=IESS-310 mode, valid with QDI, unframed, IBS, D&I, IDR.
2=EF Data legacy standard (225,205) – unframed, QDI only
3=IBS (126,112) – unframed only
EXAMPLE: <0/TRS=0 (This is a 'don't care' if no RS is selected under FEC Type)
Available all framing modes, except EDMAC.
Command or Query.
Sets or returns Tx Spectrum Invert selection in the form x, where:
0=Normal
1=Tx Spectrum Inverted
EXAMPLE:TSI=0 (selects normal)
Command or Query.
Sets or returns Tx Scrambler State in the form x, where:
0=Off
1=Normal
2=IESS-315
NOTE: When CnC mode is ON, Tx Scrambler state is fixed as IESS-315.
EXAMPLE: <0/TSC=1 (Scrambler On)
Command or Query.
Sets or returns Tx Output power level in the form xx.x, where:
Level=Value from 00 thru -40 dBm (minus sign assumed) for 950 or 1950MHz range.
Level=Value from 00 thru -25 dBm (minus sign assumed) for 50 or 180MHz range.
EXAMPLE: <0/TPL=13.4
NOTE: In AUPC mode, command is not valid. Response will be TPL*.
When APC is active, query returns "TPL=99.9"; when command is not valid, response will be TPL*.
When the external 20 dB attenuator is activated (via AUP), the permitted power level range shifted down by 20dB.
EXAMPLE: -65 and -20 dBm.
600 Emulation: Level range is from 00 thru -20 dBm (minus sign assumed).
600L Emulation: Level range is from 00 thru -45 dBm (minus sign assumed).
18=3/2 27=6/1
19=5/3 28=7/1
20=2/1 29=8/1
21=7/3 30=9/1
22=5/2 31=1/59
23=3/1 32=1/39
24=7/2 33=1/19
25=4/1
