Ideas for stepper driver control with USB-6009

[zaphead]

I have a stepper driver that takes a digital input signal for control.  Each rising edge on the driver input corresponds to one step movement.  I have two USB-6009 devices.  Is there any way to generate a digital signal with the 6009 faster than 150 Hz?  I need to output a variable freq in the range of 0 to 1 KHz.

zaphead,

Since the DIO on your 6009 is sofware timed it will output as fast as your computer can handle it.  So a faster computer and/or less going on will help things but will not get you to the 1KHz you need.  The best way to get this would be to use a different card that supports hardware timing DIO.
