®
User’s Manual
Description This command is used to select the buffer control. When NEXT is
selected, the asterisk (*) annunciator turns on to indicate that the
buffer is enabled. The storage process starts when SourceMeter is
taken out of idle to perform source-measure operations.
After the buffer stores the specified number of reading arrays (as set
by the :POINTs command), the asterisk annuciator turns off to indi
-
cate that storage is done.
With NEVer selected, storage into the buffer is disabled.
Select timestamp format
FORMat <name>
:TRACe:TSTamp:FORMat <name> Select timestamp format
Parameters <name> = ABSolute Reference to first buffer reading
DELTa Time between buffer readings
Query :FORMat? Query timestamp format
Description This command is used to select the timestamp format for buffer read-
ings. With ABSolute selected, each timestamp is referenced to the
first reading stored in the buffer. With DELTa selected, timestamps
provide the time between each buffer reading.
TRIGger subsystem
The Trigger subsystem is made up of a series of commands and subsystems to con-
figure the Trigger Model. These commands and subsystems are summarized in Table
18-11.
NOTE See Section 11, “Triggering,” for more details on triggering and the trigger
model.
Clear input triggers
CLEar
:TRIGger:CLEar Clear pending input triggers
Description When this action command is sent, any pending (latched) input trig-
gers are cleared immediately. When the SourceMeter is being trig-
gered by another instrument, it may inadvertently receive and latch
input triggers that do not get executed. These pending triggers could
adversely affect subsequent operation.
When using external triggering, it is recommended that TRIG-
ger:CLEar be sent after sending the ABORt command and at the
beginning of a program before sending an initiate command. (See
“
INITiate” command.)
