NI PXI/PCI-5401
Burst/Stepped Trigger Mode

Burst and Stepped trigger modes operate in the same fashion on the NI 5401.

After receiving a Start trigger, the waveform defined by the first stage generates until receiving another trigger. At the next trigger, the waveform of the previous stage completes before the waveform defined by the second stage generates. After the staging list completes, the waveform generation returns to the first stage and continues in a cyclic fashion.

You can use Burst trigger mode with both the Arbitrary Waveform Generation and Function Generation modes as follows:

The following figure shows a Burst trigger mode of operation for the NI 5401. Switching from stage to stage is phase-continuous. In this mode, the time instruction is not used. The trigger paces the waveform generation from one frequency to the other.
