17-98 SCPI Command Reference
Reset timestamp
:RESet
:SYSTem:TIME:RESet Reset timestamp
Description This action command is used to reset the absolute timestamp to 0 seconds.
The timestamp also resets to 0 seconds every time the SourceMeter is turned
on.
Auto reset timestamp
:RESet:AUTO <b>
:SYSTem:TIME:RESet:AUTO <b> Reset timestamp when exiting idle
Parameters <b> = 1 or ON Enable auto timestamp reset
0 or OFF Disable auto timestamp reset
Query :AUTO? Query enabled/disabled auto timestamp reset
state
Description :RES:AUTO enables or disables auto timestamp reset. When enabled, the
timestamp will be automatically reset when exiting the idle layer of the trig-
ger model. This command is intended for use with READ?/INIT when tak-
ing more than one reading.
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 compliance 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 subsystem. Note that you can use
the LLIMIT and ULIMIT commands to control auto range limits. See
SENSe1 subsystem.
