The following are some examples of good and bad commands. The examples are created from a
theoretical instrument with the simple set of commands indicated below:
[:SENSe]
:POWer
:TRIGger 
[:SEQuence]
:EXTernal [1]
[:SENSe]
:FREQuency
:POWer
[:RF]
Bad Command
PWR:ATT 40dB
The short form of POWER is POW, not PWR.
FREQ:STAR 30MHz;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
-20dBm
MIX and RANG require a colon to separate them.
:POW:ATT 40dB;TRIG:FREQ:STAR
2.3GHz
:FREQ:STAR is in the :SENSE subsystem, not the :TRIGGER subsystem.
: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
Attenuation cannot be a negative value.
