how to generate digital output signal by using DAQ 6008

[nadmal]

Hai..

Firstly i would like to thank you for the reply,i measure my ouput freq by using oscilloscope which attach at digital output terminal of DAQ 6008 card  .The suggestion that you gave is good but it only measured the simulation frequency and that frequency i already got in simulation which is in labview.the main probleam here when i measure the freq at DAQ card output terminal the freq only 10 Hz.

This document will be able to write digital signals from a DAQ USB6008 can be useful for controlling stepper motors and discrete outputs
