The output of
:READ:DIG?
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
, 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 DMM7510, 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
*RST
:TRACe:MAKE "voltDigBuffer", 10000
:DIG:FUNC "VOLTage"
:SENS:DIG:COUN 100
:READ:DIG? "voltDigBuffer", FORM, DATE, READ
:TRAC:DATA? 95,100, "voltDigBuffer"
Create a buffer named
voltDigBuffer
. Make a digitize measurement, store it in the buffer
voltDigBuffer
, and return the formatted readings, date, and reading buffer elements for the last reading
stored in
voltDigBuffer
, then return readings 95 to 100.
Example output is:
+04.963 V,09/26/2014,4.00
4.00,4.00,4.00,4.00,4.00,4.00
