16=5/4
08=2/5
17=4/3
EXAMPLE: <0/TMR=01 (Selects ratio 1/8)
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.
