5.5.10 READ Queries

The purpose of the READ? group of queries is to initiate a measurement cycle, acquire data, and return specific measurement

data. READ? performs the initiation, data acquisition, postprocessing, and data output portions of the measurement. READ?

is equivalent to ABORting any operation in progress, INITiating a new measurement, then FETChing the data when it is

ready. READ? generally does not return data unless acquisition is complete. Since READ? INITiates a new measurement

every time it is issued, READ? queries should not be used for free running data acquisition (INITiate:CONTinuous ON) - in

this case, use FETCh queries instead. The measurement is generally considered complete when the integration filter (see

SENSe:FILTer) is filled.

READ:CW:VOLTage?
