Setup 3—Using Internal PXI Trigger Lines

To handshake with multiple PXI/PXI Express switches, you can use internal PXI trigger lines. In this setup, a trigger cable is not needed between the DMM and the PXI/PXI Express switches.

  1. Open niSwitch Multi Switch Hand Int.
  2. Create scan lists according to the process described in Multiple Module Scan Lists.
  3. Set Trigger Input to the same PXI trigger line for all switches. This input line should coincide with the destination of the DMM MC signal.
  4. Set Scan Advanced Output to the same PXI trigger line for all switches. This output must coincide with the trigger source of the DMM.

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

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

  1. Connect the MC signal from the DMM to the external trigger input terminal on the front panel or in the terminal block of one 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. Open niSwitch Multi Switch Hand Ext.
  4. Create scan lists according to the process described in Multiple Module Scan Lists.
  5. Add niSwitch Route Trigger Input and niSwitch Route Scan Advanced Output before niSwitch Commit of the switch where the AUX trigger cable from the DMM is connected.
  6. Set Trigger Input Connector to Front Connector.
  7. Set Scan Advanced Output Connector to Front Connector.
  8. Set Trigger Input Bus Line to a PXI trigger line.
  9. Set Trigger Input of all the switches to the same PXI trigger line of Trigger Input Bus Line.
  10. Set Scan Advanced Output Bus Line to a different PXI trigger line.
  11. Set Scan Advanced Output of all the switches to the same PXI trigger line of Scan Advanced Output Bus Line.
  12. Set Measurement Complete Destination to External in the DMM configuration.
  13. Set Trigger Source to External in the DMM configuration.
