Is it feasible to generate a quadrature signal with an NI 9742 module?

[dj143]

I need to generate a low frequency (<1KHz) quadrature signal and am considering the NI 9742.  Does anyone know of code example to generate a quad signal that would suit well with this module or similar?  Ideally we'd be able to programmatically vary the duty cycle but it's not mandatory.  Is the NI 9742 a good choice or should we use some other cDAQ series module?

dj143,

Could you specify what you mean by quadrature signal? A square wave? Also, I was unable to find an NI 9742, however, if you meant the NI 9472, that does have access to counters which are capable of generating a square wave. Within LabVIEW, select Help>Find Examples...>Hardware Input and Output>DAQmx and there are several counter examples available.
