:FREQuency

:POWer
[ :RF]
:MIXer
:RANG e
[ :UPPer ]
Bad Command Good Command
PWR :ATT 40dB POW :ATT 40dB
The short form of POWER is POW, not PWR.
FREQ :STAR 30MHz ;MIX :RANG
-20dBm
FREQ :STAR
3 OMHz ; 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
-2OdBm
FREQ :STA R
30MHz ;POW :MIX :RANG -20dB m
MIX and RANG require a colon to separate them.
:POW :ATT 40dB ;TRIG :FREQ :STAR
2 .3GHz
:POW :ATT 40dB ; :FREQ :STAR
2 .3GH z
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 :STA R
10MHz
Attenuation cannot be a negative value .
