Description of Arguments
to Query
Command or Query.
Tx Spectrum Invert selection, where:
0=Normal,
1=Tx Spectrum Inverted
Example: TSI=0 (which is normal)

2=RTI (receive/transmit inhibit)
3=OFF due to ext H/W Tx Carrier Off command (not a valid
argument when used as a command)
4=Off due to BUC warm up delay (not a valid argument in a
command format.) Note: the front panel Tx LED will flash during
this warm-up period.
Example: TXO=1 (Tx Carrier ON)
Command or Query.
Tx Output power level between 0 and -45 dBm (minus sign
assumed).
Note: Beyond –40 dBm is beyond the specification.
Example: TPL=13.4
(Command not valid in AUPC mode)
