Resistor sorting using limit testing with multiple limits
This example inspects multiple resistors until it detects the first pass. This example uses a trigger
model using constant limits.
This trigger model provides support for inspecting the output of a single test against multiple limits.
The trigger model count block determines the number of devices that will be tested. A test refers to a
single source or measure operation. After a measurement for a particular test is performed, it is
checked against any enabled limits. The software limits are inspected in ascending numeric order
until the first pass is detected. When a pass condition is detected, the pass bit pattern assigned to the
limit that passed is output to the digital I/O port, and any subsequent limit inspections are aborted. If
all limit inspections for the test fail, the overall fail bit pattern is output.
