Multichannel Synchronization and Signal Routing in NI-DCPower

You can synchronize multiple channels with NI-DCPower by routing signals—events and triggers—from one channel to another, including channels that span multiple physical instruments.

You can export (route) the trigger and event signals to one of the physical PXI backplane trigger lines using Export Signal With Channels.

Tip You can use Wait For Event With Channels to make a channel wait to take an action until a specific event is generated.

Instead of explicitly exporting signals to physical trigger lines, NI-DCPower can automatically create routes for you. To have NI-DCPower automatically create routes, set the digital edge input terminal of one channel to be the event from another channel.

Example: Synchronizing Measure and Source Operations

To make PXI1Slot3/0 wait for the measurement of PXI1Slot3/1 to complete before PXI1Slot3/0 changes the source configuration, route the Measure Complete event of PXI1Slot3/1 to the Source trigger of PXI1Slot3/0.

To do this, configure the Source trigger of PXI1Slot3/0 to anticipate a digital edge and set the input terminal to /PXI1Slot3/Engine1/MeasureCompleteEvent.
