Tx
Reed-Solomon
Encoding
TRS= 1 byte, 0 thru 3 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.

Tx Spectrum
Invert
TSI= 1 byte, 0 or 1 Command or Query.
Sets or returns Tx Spectrum Invert selection in the form x, where:
0=Normal
1=Tx Spectrum Inverted

Tx Scrambler TSC= 1 byte, 0 thru 2 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)

Tx Power Level TPL= 4 bytes 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).
