Details
This command makes a digitize measurement using the specified function and stores the reading in a
reading buffer. Sending this command changes the measurement function to the one specified by
<function>. This function remains selected after the measurement is complete.
If you do not define the function parameter, the instrument uses the presently selected function. If a
measure function is presently selected, an error is generated.
When you use a reading buffer with a command or action that makes multiple readings, all readings
are available in the reading buffer. However, only the last reading is returned as a reading with the
command.
If you define a specific reading buffer, the reading buffer must exist before you make the
measurement.
To get multiple readings, use the :TRACe:DATA? command.
:MEASure:DIGitize? performs the same function as READ:DIGitize?.
:MEASure:DIGitize:<function>? performs the same function as sending
:SENse:DIGitize:FUNCtion "<function>", then READ?.
When specifying buffer elements, you can:
• Specify buffer elements in any order.
• Include up to 12 elements in a single list. You can repeat elements as long as the number of
elements in the list is less than 12.
• 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; not available for reading buffers that
are set to the style compact
EXTRa
Returns an additional value (such as the sense voltage from a DC voltage ratio
measurement); the reading buffer style must be set to full to use this option
FORMatted
The measured value as it appears on the front panel
FRACtional
The fractional seconds when the data point was measured
READing
The measurement reading
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
STATus
The status information associated with the measurement; see the "Buffer status bits
for sense measurements" table below
TIME
The time when the data point was measured
TSTamp
The timestamp when the data point was measured
UNIT
The unit of measure of the measurement
