If you have FORMat[:DATA] set to REAL or SREAL, you will have fewer options for buffer elements.
If you request one of the buffer elements, you will see the error 1133, "Parameter 4, Syntax error,
expected valid name parameters."
Example
:TRACe:MAKE "voltMeasBuffer", 10000
:SENSe:FUNCtion "VOLTage"
:READ? "voltMeasBuffer", FORM, DATE, READ
Create a buffer named
voltMeasBuffer
. Make a measurement, store it in the buffer
voltMeasBuffer
,
and return the formatted readings, data, and reading buffer elements for the last reading stored in
voltMeasBuffer.
Sample output is:
-00.0020 mV,05/16/2014,-2.031637E-06
