Figure 4-17: Infinite Iterative Waveform Generation with Post-trigger

In conjunction with different trigger modes and counter setups, you

can manipulate a single waveform to generate different and more

complex waveforms.

DLY2_Counter in Iterative Waveform Generation

To expand the flexibility of iterative waveform generation,

DLY2_counter was implemented to separate consecutive

waveform generations.
The DLY2_counter starts counting down right after a single

waveform generation is completed. When it reaches zero, the next

iteration of waveform generation will start as shown in Figure 4-12. If

you generate the waveform piece-wisely, the next piece of waveform

will be generated. The DLY2_counter clock source can be software

selected from internal 80 MHz Timebase.
