  • Setup 1—Using Internal PXI Trigger Lines
  • Setup 2—Using AUX Trigger Cable Connected to Front of PXI/PXI Express Switch

Setup 1—Using Internal PXI Trigger Lines

All PXI/PXI Express switches can receive an input trigger from PXI trigger lines of a PXI/PXI Express chassis. In this setup, no cable is used between the DMM and the PXI/PXI Express switch for triggering. The DMM sends its MC signal to the PXI/PXI Express switch through a PXI trigger line.

  1. Set Trigger Input to TTLn in niSwitch Configure Trigger.
  2. Set Measurement Complete Destination in niDMM Configure Measurement to the same TTLn used in niSwitch Configure Trigger.

Refer to the switch module in Devices for possible Trigger Input locations.

Setup 2—Using AUX Trigger Cable Connected to Front of PXI/PXI Express Switch

Some PXI/PXI Express switches can receive an input trigger from the front panel or terminal block. This setup uses the AUX trigger cable to trigger the switch.

  1. Connect the MC signal from the DMM to the external trigger input terminal on the front panel or in the terminal block of a PXI/PXI Express switch.
  2. Set Trigger Input to External in niSwitch Configure Trigger.
  3. Set Measurement Complete Destination to External in niDMM Configure Measurement.

Refer to the switch module in Devices for possible Trigger Input locations.
