Hello Rajesh-

I've attached an example that shows how to change frequency and/or duty cycle on-the-fly during a continuous pulse train generation with counters. It is a modified version of the example posted in the development library - NI-DAQmx Pulse Width Modulator. Rather than using property nodes, it uses the DAQmx Counter Write.vi. Either method will work for you.

I hope this helps!
