Setup 3—Using Internal PXI Trigger Lines

To handshake with a PXI/PXI Express switch, you can use the internal 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.

  1. Set Trigger Input to TTLn in niSwitch Configure Trigger.
  2. Set Scan Advanced Output to TTLm in niSwitch Configure Trigger.
  3. Set Measurement Complete Destination to TTLn in niDMM Configure Measurement Complete Destination.
  4. Set Trigger Source to TTLm in niDMM Configure Trigger.
  5. Set Sample Trigger Source to TTLm in niDMM Configure Multi Point.

Refer to the switch module in Devices for possible Trigger Input and Scan Advanced Output locations.

Setup 4—Using AUX Trigger Cable Connected to Front of PXI/PXI Express Switch

Some PXI/PXI Express switches can receive their input trigger and send their scan advanced at 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. Connect the Ext Trig In signal of the DMM to the Scanner Advanced terminal on the front panel or in the terminal block of the same PXI/PXI Express switch.
  3. Set Trigger Input to External in niSwitch Configure Trigger.
  4. Set Scan Advanced Output to External in niSwitch Configure Trigger.
  5. Set Measurement Complete Destination to External in niDMM Configure Measurement Complete Destination.
  6. Set Trigger Source to External in niDMM Configure Trigger.
  7. Set Sample Trigger Source to External in niDMM Configure Multi Point.
