Section 14: SCPI command reference
READ?
This command is typically used to acquire a post-processed reading after the instrument has been configured by
the :CONFigure command.
Usage
READ?
Details
This command is typically used to acquire a post-processed reading after the instrument has been
configured by the :CONFigure command. The :CONFigure command places the instrument in a
one-shot measurement mode. Every time the :READ? command is then sent, a measurement
conversion occurs and the reading is acquired.
When this command is sent, the following commands are executed in the order that they are
presented:
:ABORt
:INITiate
:FETCh?
When :ABORt is executed, the instrument goes into the idle state if continuous initiation is disabled.
Otherwise, operation re-starts at the beginning of the trigger model.
If the instrument is in the idle state, :INITiate takes the instrument out of the idle state. If
continuous initiation is enabled, (:INITiate:CONTinuous ON), then the :INITiate command
generates an error and ignores the command.
Use the :FETCh? for details. Note that an "Init ignored" error does not cancel the execution of the
:FETCh? command.
