18-118 SCPI Command Reference 2400 Series SourceMeter
®
User’s Manual
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 specified 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 configured to perform 10
source-measure operations 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 output enable line, over-temper
-
ature, 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 output enable to abort a test
when some condition is met. DATA? would then give the answer to
the test.
DELay <n>
:TRIGger[:SEQuence[1]]:DELay <n> Set trigger layer delay
Parameters <n> = 0 to 999.9999 Specify delay in seconds
DEFault 0 second delay
MINimum 0 second delay
MAXimum 999.9999 second delay
Query :DELay? Query the programmed delay
:DELay? DEFault Query the *RST default delay
:DELay? MINimum Query the lowest allowable delay
:DELay? MAXimum Query the largest allowable delay
Description The delay is used to delay operation in the trigger layer. After the
programmed trigger event occurs, the instrument waits until the
delay period expires before performing the Device Action.
NOTE For the Model 2430 Pulse Mode, trigger delay is not used. The Pulse Mode
uses pulse width and pulse delay for pulse timing. See
Section 5 for details
on Pulse Mode.
