NI 5411 Device Waveform Generation Triggering

The NI 5411 devices have four different operational modes that you can set

up before starting the waveform generation.

Note

Refer to the AO_Change_Parameter, WFM_Group_Control, and WFM_Load

function descriptions in the NI-DAQ Function Reference Online Help for more information

on NI 5411 operational modes.

Table 17-2.

NI 5411 Operational Modes

Mode Description

Single The waveform described by the user in the sequence

list is generated once by going through all the

sequence list. Only the start trigger is required.

Continuous The waveform described by the user in the sequence

list is generated infinitely by recycling through all the

sequence list. Only the start trigger is required.

Stepped After the start trigger is received, the waveform

described by the first sequence entry is generated.

Then, the device waits for the next trigger signal. At

triggering, the waveform described by the second

sequence entry is generated, and so on. When all of the

sequence list is exhausted, the cycle returns to first

sequence entry.

Burst After the start trigger is received, the waveform

described by the first sequence entry is generated until

another trigger is received. At triggering, the previous

waveform is completed before the waveform

described by the second sequence entry is generated,

and so on. When all of the sequence list is exhausted,

the cycle returns to the first sequence entry.
