Keithley 2002 Getting Started Manual

SCPI signal oriented commands
Signal oriented commands are used to acquire readings using a set of high-level instructions
to control the measurement process. The two most commonly used commands are
:FETCh?
and
:MEASure?
. Details on all signal oriented commands are covered in Section 3 in the User’s Man-
ual.
: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 trigger a measurement, it simply requests the last available reading.
:MEASure[:<function>]?
In general, this command places the instrument in the “one-shot” measurement mode (ARM
indicator off), triggers a single measurement, and then performs a
:FETCh?
.
If you include the measurement function with this command, the instrument will first go to
the specified function and then perform the one-shot measurement and query, as follows:
:MEASure?
Currently selected function
:MEASure:VOLTage:DC?
DCV function
:MEASure:VOLTage:AC?
ACV function
:MEASure:CURRent:DC?
DCI function
:MEASure:CURRent:AC?
ACI function
:MEASure:RESistance?
Ω 2 function
:MEASure:FRESistance?
Ω 4 function
:MEASure:FREQuency?
FREQ function
:MEASure:TEMPerature?
TEMP function
IEEE-488 Bus Operation 3-11
