NI-DCPower Named Trigger Types

Named trigger types in NI-DCPower define the action you want an instrument or instrument channel to take upon detecting a specific signal condition.

The following named triggers are available for NI-DCPower instruments:

  • Start—In Sequence source mode, a channel waits for a Start trigger upon entering the Running state; receiving the Start trigger causes a channel to begin source and measure operations.

    A channel does not perform any source or measure operations until it receives this trigger.

    This trigger is not used in Single Point source mode.

  • Source—Receiving a Source trigger causes a channel to modify the source configuration.

    This trigger is available only when sourcing DC voltage or DC current.

  • Measure—Receiving a Measure trigger, if Measure When is set to On Measure Trigger, causes a channel to take a measurement.

    A channel ignores this trigger if a measurement is already in progress or if Measure When is set to a different value.

  • Sequence Advance—In Sequence source mode, a channel waits for the Sequence Advance trigger once an iteration of a sequence completes; receiving a Sequence Advance trigger causes the channel to begin the next iteration of the sequence.

    Sequence Loop Count must be set to a value greater than one for a sequence to iterate, and thus for this trigger to occur.

    This trigger is not used in Single Point source mode.

  • Pulse—Receiving a Pulse trigger causes a channel to transition from the pulse bias level to the pulse level.

    This trigger is available only when sourcing pulse voltage or pulse current.

  • Shutdown—Receiving a Shutdown trigger causes the output relay of a channel to open, which completely interrupts output on that channel. The channel must be reset to resume operation.
