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

  • 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 switches for triggering. The DMM sends its MC signal to the PXI/PXI Express switches through a PXI trigger line.

  1. Open niSwitch Multi Switch Synch 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.

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 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. Open niSwitch Multi Switch Sync Ext.
  3. Create scan lists according to the process described in Multiple Module Scan Lists.
  4. Add niSwitch Route Trigger Input to the configuration of the switch where the AUX trigger cable from the DMM is connected.
  5. Set Trigger Input Connector to Front Connector.
  6. Set Trigger Input Bus Line to TTLn.
  7. Set Trigger Input to the same TTLn for all switches.
  8. Set Measurement Complete Destination to External in the DMM configuration.
