how to generate digital signal from PCI-6221 like the one shown in the picture

[030002]

I am required to generate a signal from the PCI-6221 board like the one shown in the figure below.

I am being succesfull generating the latter part of the signal for which the frequency is 200us and duty cycle 0.5%. I have attached the labview file.

th program should be like this when button is switched ON digital signal is created with the frequency and duty cycle as given by user in teh front panel and when the switched OFF then the above signal that is frequency 200us duty cycle 0.5% is generated.

Kindly tell me how can i implement the second part ?

Hi Ali,

What you can do is place a DAQmx property node to manipulate the frequency and duty cycle of the generated signal, as shown in the digram below:

You can also find an example that is related to your question, as shown in the link below.
