what is the maximum rate we can achieve using 9403 in digital switching?

 i am using 9102 chassi and 9012 controller.

 i am trying to program the 9403 as the output port and i am using it for switch on one of my devices.

                      minimum pulse width should be =1micro second

Have you looked at the specifications in the user manual for the 9403?

Looks likethe update rate for the 9403 using a cRIO 9102 chassis is 7microsec.  I don't think you can get 1 microsec pulse width using the 9403, maybe try the 9401 or other high-speed module.
