A test systemthat can accept a plurality of plug-in electronic cards in Xi Slotsor PXI slotsis described. The test or source measure switching systemincludes a sequencer or sequence enginewhich is fully capable of executing opcode instructions having potentially indefinite completion times and monitoring multiple asynchronous inputs simultaneously without interrupts. The sequenceris sequential and deterministic to approximately 10 microsecond resolution. The sequencerincludes a trigger router which can be a fully configurable trigger input and trigger output routing matrix. Every trigger input can be configured via several detection modes such as active high, active low, level high and level low. Also, trigger outputs can be configured to be triggered on single, multiple or auto triggers if set.

The test or source measure switching systemincludes a sequencer or sequence enginewhich is fully capable of executing opcode instructions having potentially indefinite completion times and monitoring multiple asynchronous inputs simultaneously without interrupts. The sequenceris sequential and deterministic to approximately ten microsecond resolution.
