Operation Theory 43
Stop Modes
You may stop waveform generation while it is still in progress,
either by hardware or software trigger. The stop trigger sources
can be software selected from internal software trigger, exter-
nal digital trigger (AFI-0/1), or analog trigger. Three stop modes
are provided to stop finite or infinite waveform generation.
Stop Mode I
After a mode I stop trigger is asserted, the waveform genera-
tion stops immediately. Figure 4-14 illustrates this example.
Figure 4-14: Stop Mode I
Stop Mode II
After a mode II stop trigger is asserted, the waveform genera-
tion continues to generate a complete waveform, then stops
the operation.Figure 4-15 is an example of Stop Mode II. Since
UC_counter is set to four, the total generated data points must
be a multiple of four.
You can check WFG_in_progress (waveform generation in
progress) status by software read-back to confirm the stop of a
waveform generation.
