Details
This query makes the number of readings specified by
[:SENSe[1]]:COUNt
. If multiple readings
are made, all readings are available in the reading buffer. However, only the last reading is returned
as a reading with the command. To get multiple readings, use the
:TRACe:DATA?
command.
To change the number of digits returned in a remote command reading, use the
:FORMat:ASCii:PRECision
command.
If you define a specific reading buffer, the reading buffer must exist before you make the
measurement.
When specifying buffer elements, you can:
•
Specify buffer elements in any order.
•
Include any or all of the buffer elements listed below in a single list. You can repeat elements as
long as the number of elements in the list is less than 14.
•
Use a comma to delineate multiple elements for a data point.
The options for
<bufferElements>
are described in the following table.
Option Description
DATE
The date when the data point was measured
FORMatted
The measured value as it appears on the front panel
FRACtional
The fractional seconds for the data point when the data point was measured
READing
The measurement reading based on the SENS:FUNC setting; if no buffer elements
are defined, this option is used
RELative
The relative time when the data point was measured
SEConds
The seconds in UTC (Coordinated Universal Time) format when the data point was
measured
SOURce
The source value; if readback is ON, then it is the readback value, otherwise it is the
programmed source value (see :SOURce[1]:<function>:READ:BACK (on page 6-99))
SOURFORMatted
The source value as it appears on the display
SOURSTATus
The status information associated with sourcing. The values returned indicate the
status of the following conditions:
•
Overvoltage protection was active
•
Measured source value was read
•
Overtemperature condition existed
•
Source function level was limited
•
Four-wire sense was used
•
Output was on
SOURUNIT
The unit of value associated with the source value
STATus
The status information associated with the measurement; see the "Buffer status bits
for sense measurements" table below
TIME
The time for the data point
TSTamp
The timestamp for the data point
UNIT
The unit of measure associated with the measurement
