50us pulse with USB 6501

[trekman]

I am trying to use a USB6501 in an application that requires creating a 50us pulse.  I tried creating a loop with a simple inverting function and shift registers to create a pulse train but when I looked at the signal on an oscilloscope the pulse width was only 7ms.  Is it possible to get a 50u pulse?

Not a chance. As the specs state, you only have software timed I/O with that card. The counter does not have pulse generation capability either.

What card would you reccomend then that has the capability to create a 50us pulse aswell as the ability to switch the lines from input to output?

I try not to give specific hardware recomendations. You can contact your local NI Sales Engineer where you can provide more details (i.e. number of lines, etc.). You would want a card that has either a counter that can be configured to output a pulse or a card with hardware timed digital i/o.
