Pulse Generation Timing Considerations
Figure 2-9 shows pulse generation timing for both the TC toggled output and TC pulse output
cases. These signals are positive polarity output signals.
Figure 2-9.
Pulse Generation Timing
An uncertainty is associated with the delay period due to counter synchronization. Counting
starts on the first timebase edge after NI-DAQ applies the starting signal. The time between
receipt of the starting pulse and start of pulse generation can be between (delay) and
(delay + 1) units of the timebase in duration.
