3.11 Signal oriented measurement commands

The signal oriented command group is used to acquire readings using a set of high-level instructions to control the measurement
process. These commands are summarized in Table 3-3.

Command

:CONFigure:<function>
:READ?
:MEASure[:<function>]?
Description
Program fragment
Query
Description
Requests the latest reading.
Places the 2002 in a "one-shot" measurement mode for the specified function.
Performs an :ABORt, :INITiate, and a :FETCh?.
Performs an :ABORt, :CONFigure:<function>, and a :READ?.
:FETCh?
This query command is used to request the latest post-processed reading. After sending this
command and addressing the Model 2002 to talk, the reading will be sent to the computer. This
command does not affect the instrument setup.
This command does not trigger a measurement. It simply requests the last available reading.
Note that this command can repeatedly return the same reading. In the absence of a new reading,
this command will simply return the old reading. If your application requires "fresh" readings,
use the :DATA:FRESh? command (see SENSe Subsystem).
This command is automatically asserted when the :READ? or :MEASure? command is sent.
PRINT #1, "output 16; :syst:pres"
PRINT #1, "output 16; :fetch?"
PRINT #1, "enter 16"
:CONFigure:<function>
where: <function> = VOLTage:DC
