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 3000 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 3000.
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 Model 6482 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 3000. If, for exam-
ple, 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? through CALC7: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.
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.
