The waveform thus produced at the counter’s output can be used to provide
timing for undersampling applications where a digitizing system can
sample repetitive waveforms that are higher in frequency than the Nyquist
frequency of the system. Figure 7-29 shows an example of pulse generation
for ETS; the delay from the trigger to the pulse increases after each
subsequent Gate active edge.

Counter Timing Signals
S Series devices feature the following counter timing signals:
•
•
•
•
•
•
•

Counter n Internal Output Signal

•
In this section, n refers to either Counter 0 or 1. For example, Counter n
Source refers to two signals—Counter 0 Source (the source input to
Counter 0) and Counter 1 Source (the source input to Counter 1).
