Model 2461 Interactive SourceMeter® Instrument Reference Manual

The output of
:MEASure:DIGitize?
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
floating-point numbers 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
Model 2461, this will always be 0 (main) or 2 (digitizer)
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
TRACe:MAKE "voltDigitizeBuffer", 10000
MEAS:DIG:VOLT? "voltDigitizeBuffer", FORM, DATE, READ
Create a buffer named
voltMeasBuffer
. Make a digitize voltage reading and store it in the buffer
voltMeasBuffer
and return the formatted reading, the date, and the reading elements from the buffer.
Example output:
-00.0024 mV,05/16/2014,-2.384862E-06

Usage
:READ?
:READ? "<bufferName>"
:READ? "<bufferName>", <bufferElements>
<bufferName>
The name of the buffer where the reading is stored; if nothing is specified,
defbuffer1
is used
<bufferElements>
See
Details
; if nothing is specified,
READing
is used
