SCPI Command Reference 17-103
Abort source/measure cycle
:ABORt
Abort operation
Description
When this action command is sent, the SourceMeter aborts operation and
returns to the idle state.
A faster way to return to idle is to use the DCL or SDC command.
With auto output-off enabled (:SOURce1:CLEar:AUTO ON), the output
will remain on if operation is terminated before the output has a chance to
automatically turn off.
Program trigger model
:COUNt <n>
:ARM[:SEQuence[1]][LAYer[1]]:COUNt <n> Set arm count
:TRIGger[:SEQuence[1]]:COUNt <n> Set trigger count
Parameters
<n> = 1 to 2500 Specify count (see NOTE)
DEFault Sets count to 1
MINimum Sets count to 1
MAXimum See NOTE
INFinite (ARM:COUNt only)
NOTE
The product of arm count and trigger count cannot exceed 2500.
Query
:COUNt? Queries programmed count
:COUNt? DEFault Queries *RST default count
:COUNt? MINimum Queries lowest allowable count
:COUNt? MAXimum Queries largest allowable count
Description
This command is used to specify how many times an operation is performed
in the speci
fi ed layer of the trigger model.
For example, assume the arm count is set to 2 and the trigger counter is set
to 10, the SourceMeter is con
fi gured to perform 10 source-measure opera-
tions twice for a total of 20 source-measure operations.
The product of the arm count and trigger count cannot exceed 2500. If, for
example, the arm count is 2, then the maximum trigger count is 1250.
NOTE
INFinite can be used only with ARM:COUNt, and FETCh?, READ?, MEAS?,
CALC1:DATA?, or CALC2:DATA? cannot be used with infinite arm count. Only
INIT will start measurements, and only interlock, over-temperature, SDC, DCL, or
ABORt should be used to stop the sweep.
ARM:COUNt INFinite can be used for repetitive source waveforms or for
long tests where only the last reading is important. For example, the limits
could be used to drive the interlock to abort a test when some condition is
met. DATA? would then give the answer to the test.
