PWR:ATT 40dB

POW:ATT 40dB

 

 

The short form of POWER is POW, not PWR.

 

 

 

FREQ:STAR 30MHz;MIX:RANG –20dBm

FREQ:STAR 30MHz;POW:MIX:RANG

 

–20dBm

 

 

The :MIX:RANG command is in the same :SENSE subsystem as :FREQ, but executing

the :FREQ command puts you back at the

:SENSE level. You must specify :POW to

get to the :MIX:RANG command.

 

 

 

 

 

FREQ:STAR 30MHz;POW:MIX RANG

 

FREQ:STAR 30MHz;POW:MIX:RANG

:MIX and :RANG require a colon to separate them.

 

 

 

:POW:ATT 40dB;TRIG:FREQ:STAR

 

:POW:ATT 40dB;:FREQ:STAR

:FREQ:STAR is in the :SENSE subsystem, not the :TRIGGER subsystem.

 

 

 

:POW:ATT?:FREQ:STAR?

 

:POW:ATT?;:FREQ:STAR?

 

 

 

:POW and :FREQ are within the same :SENSE subsystem, but they are two separate commands, so they should be separated with a semicolon, not a colon.

:POW:ATT -5dB;:FREQ:STAR 10MHz

:POW:ATT 5dB;:FREQ:STAR 10MHz

 

 

Attenuation cannot be a negative value.
