CALCulate[1]|2|3|4:FEED[1]2?
The query returns the current value of the string.
Item Description Range of Values
string The input measurement type to be fed to the specific input on the CALC block:
– PEAK: peak power
– PTAV: peak to average
– AVER: average
– MIN: minimum power
Values may be followed by ON SWEEP[1]|2|3|4 where the numeric
specifies the gate to be used for the feed. For example: “POW:PEAK ON
SWEEP2”.
If ON SWEEP[1]|2|3|4 is not supplied, the gate used is left unchanged.
A feed of “” (empty string) disables the CALC block and switches off that
display line.
“POW:PEAK”
“POW:PTAV”
“POW:AVER” “POW:MIN”
CALC3:FEED2 “POW:AVER ON
SWEEP2”
This command selects the input for FEED2
of CALC block CALC3 to be average power,
using gate 2. The channel from which the
feed is taken is determined by
