When the statistics operations are disabled, sending this command will not perform the statistic
operations. However, it will return the last calculation results. If the specified statistics calculations
have never been performed, the instrument returns
-1.37
.
If the buffer is empty, the instrument returns
-1.37
.
If you send the query command:
:CALCulate2:IMMediate?
, the instrument performs the following
two actions:
Finishes the selected statistic operation.
Reads the calculation results.
Example
*RST
:TRAC:CLE
:TRIG:COUN 10
:VOLT 6
:OUTP ON
:INIT
*OPC?
:CALC2:STATE ON
:CALC2:FUNC VOLT
:CALC2:FORM:ELEM "READ,UNIT,TST,RNUM"
:CALC2:FORM MIN,MAX
:CALC2:IMM?
:CALC2:FORM MIN,MAX,MEAN,PKPK,SDEV
:CALC2:IMM?
:CALC2:FORM MAX,SDEV
:CALC2:DATA?
Before the calculation, start the trigger model to take 10
readings.
The first
CALC2:IMM?
returns reading, units, timestamp
and reading number for MIN and MAX:
5.00V,06/25/2013
09:39:31.4455,0008RNDG#,5.00V,06/25/2013
09:39:30.7283,0001RNDG#
The second
CALC2:IMM?
only returns reading and units
for MIN, MAX, MEAN, PKPK and SDEV:
5.00V,5.00V,5.00V,1.360
893E-03V,4.204334E-04V
CALC2:DATA?
returns reading and units for MAX and
SDEV: 5.00V,4.204334E-04V
