DAQArb 5411 User Manual
You can use continuous trigger mode with the both the Arb and DDS
waveform generation modes, as follows:
•
Arb mode—Figure 4-11 uses the stages shown in Figure 4-4 to
illustrate a continuous trigger mode of operation for Arb waveform
generation mode.
End of All Stages
Figure 4-11. Continuous Trigger Mode for Arb Mode
•
DDS mode—Figure 4-12 illustrates a continuous trigger mode of
operation for DDS waveform generation mode.

Figure 4-12. Continuous Trigger Mode for DDS Mode
Stepped Trigger Mode
After a start trigger is received, the waveform described by the first
stage is generated. Then, the device waits for the next trigger signal. On
the next trigger, the waveform described by the second stage is
generated, and so on. Once the staging list is exhausted, the waveform
generation returns to the first stage and continues in a cyclic fashion.
You can use the stepped trigger mode with the both the Arb and DDS
waveform generation modes, as follows:
•
Arb mode—Figure 4-13 uses the stages shown in Figure 4-4 to
illustrate a stepped trigger mode of operation for the Arb mode. If
a trigger is received while a stage is being generated, it will be
ignored. A trigger will be recognized only after the stage has been
completely generated.
