The output of :FETCh? is affected by the data format selected by :FORMat[:DATA]. If you set
FORMat[:DATA] to REAL or SREAL, you will have fewer options for buffer elements. The only buffer
elements available are READing, RELative, SOURce, and EXTRa. If you request a buffer element
that is not permitted for the selected data format, the instrument generates the error 1133, "Parameter
4, Syntax error, expected valid name parameters."
The STATus buffer element returns status values for the readings in the buffer. The status values ar
e
i
ntegers that encode the status value. Refer to the following table for values.
Buffer status bits for sense measurements

0x0080
STAT_LIMIT1_HIGH
128
Measure status limit 1 high
0x0100
STAT_START_GROUP

First reading in a group
Example
FETCh? "defbuffer1", DATE, READ
Retrieve the date and measurement value for the most recent
data captured in defbuffer1.
Example output:
