13-2 Remote Operations

Differences: remote vs. local operation

Operation enhancements (remote operation)
There are some source-measure operations you can do over the IEEE-488 bus and RS-232
interface that you cannot do from the front panel; these are summarized below.
Math expressions
There are five math expressions available from the panel. All except the Percent Deviation
are available as pre-defined math expressions for remote operation. However, remote operation
allows you to create up to five user-defined math expressions for a total of nine expressions. An
example program shows how to create Percent Deviation as a user-defined math expression.
Concurrent measurements
With the use of the TOGGLE key, you can measure (display) two functions concurrently.
Using remote operation, you can perform concurrent measurements on all three functions (volt-
age, current, and resistance). See Section 17, SENSe1 Subsystem for details.
Local-to-remote transition
When changing from local to remote operation, the following actions occur:
•
•
•
•
•
•
•
•
The SourceMeter stops performing source-measure operations and returns to the idle
state (ARM annunciator off).
All sweep operations are aborted.
All menus are exited.
All pending front panel commands are aborted.
Source and compliance editing are disabled.
Data in the sample buffer is lost (i.e., :FETCh?, :CALC1:DATA?, and :CALC2:DATA?
will not return any data until readings are taken while in remote).
Concurrent measurements are enabled.
All other settings are not affected, including those for the :TRACe buffer (data store).
