Remote Operation
CALCulate Subsystem Commands
CALCulate[1|2|3|4|5|6]:MEAN:STATe OFF|ON|0|1
CALCulate[1|2|3|4|5|6]:MEAN:STATe?
Turns the mean power calculation for a trace
ON
or
OFF
. Only one mean power
calculation can be turned on at a time. For example, if a mean power calcula-
tion is being performed on trace A, turning a mean power calculation for
trace B
ON
will turn the calculation for trace A
OFF
.
CALCulate[1|2|3|4|5|6]:MINimum:CLEar
Clears the current minimum hold values for the trace and allows a new mini-
mum hold to occur. The trace will be initialized to the current value of the
trace. If the specified trace is not in the minimum hold state, sending this com-
mand will have no effect.
CALCulate[1|2|3|4|5|6]:MINimum[:STATe] OFF|ON|0|1
CALCulate[1|2|3|4|5|6]:MINimum[:STATe]?
Turns minimum hold for a trace
ON
or
OFF
. The minimum hold operation com-
pares the current amplitude value of each point on a trace in the current
sweep to the corresponding point detected during the previous sweep, then
stores the minimum value. The CALCulate:AVERage, CALCulate:MAXimum,
and CALCulate:MINimum states are mutually exclusive. Each trace can have
only one of these functions on at a time. Turning CALCulate:MINimum
ON
will
automatically turn CALCulate:AVERage and CALCulate:MAXimum
OFF
. Each
trace can have a different CALC block turned on. For example,
CALCulate1:MAXimum
ON
, CALCulate2:MINimum
ON
, CALCulate3:AVERage
ON
will put trace A in maximum hold, trace B in minimum hold, and trace C in
trace average mode.
If the math expression with the corresponding CALCulate subopcode is
OFF
,
then the SENSe:DATA is used for the minimum hold operation. If the math
expression is
ON
, the result of the math expression is used for the minimum
hold operation.
CALCulate:THReshold <param>[W|MW|UW|DBM]
CALCulate:THReshold?
Sets the value for the marker search threshold.
