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.
