The example is to demonstrate how to insert the frequency parameters while the VI is already running
Using the event structure, the VI would work to generate a pulse train signal with a pre defined frequency and would change the output's frequency as soon as the user change the parameters while the VI is running

I implemented this VI with a SensorDAQ interface. One problem is that the SensorDAQ does not support on-the-fly frequency changes, so that I have to stop the task, change the frequency and restart the task--not terribly serious for my application. More serious is the fact that the actual frequencies I get are all integral fractions of the interface's maximum frequency. That means I get either 366.2109 Hz or 183.1055 with nothing in between. Is there any way to get arbitrary frequencies (say, 200 Hz 250 Hz)
