Configuration of the E8491A external ‘Trig In’ and ‘Trig Out’ ports is done through the HP I_O Libraries’ ‘I_O Config’ utility. This portion of the utility is shown in the following figure.

Figure 3-1. Configuring the HP E8491A External Trigger Ports.

When ‘External Trig In’ is selected, the faceplate ‘Trig In’ port is configured for the trigger level and state (normally high or normally low) selected. When ‘External Trig Out’ is selected, the faceplate ‘Trig Out’ port is configured for the state (normally high or normally low) selected.

1. Trigger routing is only available using the HP SICL ivxitrigroute function.
