CALCulate3
Select statistic
FORMat <name>
:CALCulate3:FORMat <name> Specify CALC3 format
Parameters <name> = MEAN Mean value of readings in buffer
SDEViation Standard deviation of readings in
buffer
MAXimum Largest reading in buffer
MINimum Lowest reading in buffer
PKPK MAXimum - MINimum
Query :FORMat? Query programmed math format
Description This command is used to select the desired statistic on readings
stored in the buffer. See
Section 9, “Data Store,” for details on these
statistics.
Readings stored in the buffer can be “raw” measured readings, the
results of the CALC1 calculation, or CALC2 readings. The
:TRACe:FEED command in the :TRACe Subsystem is used to select
the type of readings to store.
Acquire statistic
:DATA?
:CALCulate3:DATA? Read CALC3 result
Description This query command is used to perform the selected statistic opera-
tion and read the result(s). The result(s) is always returned in ASCII
format.
If the buffer is configured to store raw measured readings
(:TRACe:FEED SENSe1) and multiple functions were measured, the
selected statistic operation will be performed on all the measured
readings. For example, if voltage and current measurements were
stored in the buffer, then the selected statistic operation will be per
-
formed on both readings. Statistics for multiple measurement func-
tions are returned in the following order:
voltage statistic, current statistic, resistance statistic.
Statistic operations are not performed on TIME and STATus data ele-
ments that are stored in the buffer.
