When using the SCPI interface, this command does not affect the Questionable Event Enable
Register or Operation Event Enable Register sets.
Status model programming examples
The following examples illustrate how to generate an SRQ using the status model.
SRQ when the SMU reaches its source limit
This example demonstrates how to generate a service request (SRQ) when the source-measure unit
(SMU) detects it has reached its source limit. After configuring the status model, in this example the
source will be configured to output current and measure voltage. If the output terminals of the SMU
are left open when running this example, the SMU will reach its source limit and generate an SRQ.
