How do I generate a pulse with a user specified puse duration, down time and repitition, and then out put to a graph?

How do I generate a pulse with a user specified puse duration, down time and repitition, and then out put to a graph and then to daq ports? 

I used lab view in engineering class, but that was the extent of my usage and after fiddling around in lab view and looking on the web looking for solution, I could not produce desired results.  My professor wants me to produce something that will output a pulse for a specified duration, then downtime for another specified duration and then repeat the process a specified amount of times.  

I am using labview version 7.1

Thanks in advance.

Hello,

Are you using hardware (DAQ card) to generate this pulse or are you planning on doing this all in software.  If you have a DAQ card in LabVIEW you can go to Help » Find Examples and then select Hardware Input and Output » DAQmx » Generating Digital Pulses » Gen Dig Pulse Train-Finite.vi.  This will use a counter from your DAQ card to generate a finite number of pulses at a specified frequency and duty cycle.  Give this a try, or let me know if you are not using hardware, and we can figure something else out.
