This command is used to specify how many times an operation is per-
formed 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 2500 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 example, the arm count is 2, then the maximum trigger count is
1250.
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 con-
dition is met. :DATA? would then give the answer to the test.
