One-Button Measurement Functions
READ Commands:
:READ:<measurement>[n]?
• Does not preset the measurement to the factory default settings. For example, if you have
previously initiated the ACP measurement and you send READ:ACP? it will initiate a new
measurement using the same instrument settings.
• Initiates the measurement and puts valid data into the output buffer. If a measurement other
than the current one is specified, the instrument will switch to that measurement before it
initiates the measurement and returns results.
For example, suppose you have previously initiated the ACP measurement, but now you are
running the channel power measurement. Then you send READ:ACP? It will change from
channel power back to ACP and, using the previous ACP settings, will initiate the
measurement and return results.
• Blocks other SCPI communication, waiting until the measurement is complete before
returning the results
If the optional [n] value is not included, or is set to 1, the scalar measurement results
will be returned. If the [n] value is set to a value other than 1, the selected trace data
results will be returned. See each command for details of what types of scalar results
or trace data results are available. The binary data formats should be used when
handling large blocks of data since they are smaller and faster then the ASCII
format. (FORMat:DATA)
