Description of Arguments
to Query
Command or Query
Tx Alpha Rolloff, where:
1 = 25%
2 = 35%
Example: TAR=1 (which is a Tx Alpha Rolloff of 25%)
Command or Query.
Tx Spectrum Invert selection, where:
0=Normal,
1=Tx Spectrum Inverted
Example: TSI=0 (which is normal)
Command or Query.
Tx Scrambler state, where:
0=Off
1=On
Example: TSC=1 (Scrambler On)
Command or Query.
Tx Output power level, where:
s=sign ( + / - )
xx.x = Tx Output power level,
L-Band unit: +00.0 and –20.0 dBm.
70/140 MHz unit: +00.0 to –20.0 dBm
Note: Beyond –20 dBm is beyond the specification.
Example: TPL = -13.4
Command or Query.
Tx output impedance, where:
0=50 Ohm
1=75 Ohm
(Valid for 70/140 MHz units only)
Example: IMP=1 (Set impedance to 75 Ohms)
