Learn what a sequence is, when to use it, and how NI-DCPower maps channels, terminals, and events in Sequence Source Mode.
What a Sequence is
A sequence is a series of steps that apply voltage or current values on a NI-DCPower channel. In a simple sequence, each step sets a voltage or current level. Advanced sequencing lets you configure multiple properties per step.
To customize per-step properties, see Advanced Sequencing.
Deterministic Operation
During a sequence, the channel steps through a predefined set of NI-DCPower configurations without any interaction with the host system or NI-DCPower.
Because the host system does not execute the NI-DCPower sequence changes, the transitions from one step in the sequence to the next are deterministic.
Support for Sequence Source Mode
- The following instruments do not support Sequence Source Mode on any channel:
- PXI-4110
- PXI-4130
- The system does not support using the NI-DCPower Set Sequence and Advanced Sequence functions for the same channel in the same session.
