Single Point Source Mode

In Single Point source mode, the source unit applies a single source configuration when it enters the Running state. You can then update the source configuration dynamically.
Single Point Source Model
The following steps illustrate the typical operation of the source unit when you initiate in Single Point source mode:
- (Optional) The source unit waits for a Source trigger.
- The source unit updates the source configuration.
- After waiting the time specified by the NI-DCPower Source Delay property, the
source unit generates a Source Complete Event, as
illustrated in the following figure.

- (Optional) If the NI-DCPower Measure When property is set to
Automatically After Source
Complete, the measure unit takes a
measurement after the Source Complete event generates.

Note In Single Point source mode, only
the Source trigger is available to control the source unit.
Accordingly, the Sequence Advance trigger is not available, and
Start trigger must be set to None.
Note The PXI-4110 and PXI-4130 do not
support triggers and events or automatically measuring after source
complete. On these devices, after entering the Running state, the
source unit simply updates the source configuration without waiting
for any triggers or generating any events, and the measure unit
cannot automatically take a measurement after the source completes.

A sequence is composed of steps that specify a series of outputs for an NI-DCPower channel. In a simple sequence, you can specify either a series of voltage outputs or a series of current outputs. Advanced sequencing allows you to configure multiple properties per sequence step.
