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 are
integers that encode the status value. Refer to the following table for values.
Buffer status bits for sense measurements
Bit (hex) Name
Decimal Description
0x0001 STAT_QUESTIONABLE
1
Measure status questionable
0x0006 STAT_ORIGIN
6
A/D converter from which reading originated; for the
2470, this will always be 0 (main)
0x0008 STAT_TERMINAL
8
Measure terminal, front is 1, rear is 0
0x0010 STAT_LIMIT2_LOW
16
Measure status limit 2 low
0x0020 STAT_LIMIT2_HIGH
32
Measure status limit 2 high
0x0040 STAT_LIMIT1_LOW
64
Measure status limit 1 low
0x0080 STAT_LIMIT1_HIGH
128
Measure status limit 1 high
0x0100 STAT_START_GROUP
256
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:
03/21/2013,-1.375422E-11
