square wave aquisition in which rising and falling time should be zero

[pani]

Hiii frnz.

            Iam acquiring square wave using analog input. Here i have to find out the dutycycle. The DAQ iam using is 6215.

The signal frequency is 12k. The prob here is with rising time and falling time of the signal. For a perfect signal the rising

nd falling time is zero. But here it shows some milli seconds. Because of which the duty cycle varies. Here iam attatchng

the VI..Look it out and help me with this.
