Keysight M9037A PXIe Embedded Controller User Guide 21M9037A Functional Description IntroductionSoftware generated trigger to selected backplane trigger bus and front panel SMB triggerconnectorTrigger Source:Software GeneratedTrigger Destination:One of the eight PXI backplane trigger lines and the frontpanel SMB trigger connectorIVI Driver Syntax (C#):TriggerRouting.SetRoute (AgPxiPcTriggerRouteEnum.AgPxiPcTriggerRouteSoftwareToTriggerBusAndExternal,AgPxiPcPxiTrigEnum.AgPxiPcPxiTrig[0:7])To set the software trigger level use the property:TriggerRouting.SoftwareRouteTriggerStateFor example, to create a negative-going edge ( ):TriggerRouting.SoftwareRouteTriggerState = true;TriggerRouting.SetRoute (AgPxiPcTriggerRouteEnum.AgPxiPcTriggerRouteSoftwareToTriggerBusAndExternal,AgPxiPcPxiTrigEnum.AgPxiPcPxiTrig[0:7]);TriggerRouting.SoftwareRouteTriggerState = false;Notes:• A “software trigger” does not generate a trigger pulse. The SoftwareRouteTriggerState property in the IVI driver definesa voltage level: True = 3.3V (asserted) and False = 0.0V (not asserted). To generate a pulse, you must toggle the stateof the SoftwareRouteTriggerState property; that is, set the property to one state, wait for the desired length of pulse,and then set the property to the opposite state.• You must select one of the eight PXI backplane trigger bus lines (TTL TRIG[0:7]). The software-generated trigger signalwill be active on the selected backplane trigger bus line and thus available to any PXI module installed in the chassis.You cannot select only the front panel SMB trigger connector as a trigger destination without selecting one of the PXIbackplane trigger bus lines.• TriggerRouting.Enabled returns “true” if and only if the trigger routing subsystem is enabled.• Use TriggerRouting.RouteConfiguration to determine the current routing configuration.• TriggerRouting.ResetRoute opens all trigger routing paths and disables the trigger routing subsystem. ResetRoute doesnot alter the state of the SoftwareRouteTriggerState property. However, the Reset method of the IVI driver resets thestate to the power-on default of True (3.3V).• The front panel TRIG port connects directly to Trigger Bus Segment 1 on the PXIe chassis Backplane.
