2400 Series SourceMeter
®
User’s Manual SCPI Command Reference 18-117
Auto range change mode
RCMode <name>
:SYSTem:RCMode <name> Control auto range change mode
Parameters <name> = SINGle Single mode
MULTiple Multiple mode
Query :RCMode? Query auto range change mode
Description This command controls the auto range change mode. In the SINGle
mode, the SourceMeter will auto range only after first taking a reading.
In the MULTiple mode, the SourceMeter will auto range up on compli-
ance in the Delay phase of the Source-Delay-Measure cycle, thereby
minimizing the chance of a SourceMeter being in compliance in a
multiple-SourceMeter system. A SourceMeter can downrange only once
a reading has been taken. In the MULTiple mode, you can control the
soak time using the :SOUR:SOAK command. (See “SOURce sub-
system.”) Note that you can use the LLIMIT and ULIMIT commands to
control auto range limits. (See “SENSe1 subsystem.”)
TRACe subsystem
The commands in this subsystem are used to configure and control data storage into the
buffer. The commands are summarized in Table 18-10.
:TRACe|:DATA
The bar (|) indicates that :TRACe or :DATA can be used as the root command for this sub-
system. From this point on, the documentation in this manual uses :TRACe. If you prefer
to use :DATA, simply replace all the :TRACe command words with :DATA.
Read and clear buffer
DATA?
:TRACe:DATA? Read contents of buffer
Description When this command is sent and the SourceMeter is addressed to talk, all
the readings stored in the data store are sent to the computer.
The format used to send readings over the bus is controlled from the
:FORMat subsystem.
