Usage
:MEASure?
:MEASure:<function>?
:MEASure:<function>? "<bufferName>"
:MEASure:<function>? "<bufferName>", <bufferElements>
:MEASure? "<bufferName>"
:MEASure? "<bufferName>", <bufferElements>
<function>
The measure function:
• Current: CURRent[:DC]
• Resistance: RESistance
• Voltage:
VOLTage[:DC]
<bufferName>
The name of the buffer where the reading is stored; if nothing is specified,
defbuffer1
is used
<bufferElements>
See Details
Details
This command makes a measurement using the specified function and stores the reading in a
reading buffer.
If you do not define the function parameter, the instrument uses the presently selected measure
function.
This query makes the number of readings specified by [:SENSe[1]]:COUNt. 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.
Sending this command changes the measurement function to the one specified by <function>.
This function remains selected after the measurement is complete.
:MEASure? performs the same function as READ?.
:MEASure:<function>? performs the same function as sending :SENse:FUNCtion, then READ?.
