myDAQ frequency generation beyond 20 kHz

[bentwookiee]

I am looking into purchasing a myDAQ, as we use LabVIEW at school and my job.  I noticed the frequency generator only goes up to 20 kHz.  Is this a limitation of the hardware or the student software?  If it is merely a software limit, would the full version circumvent this limitation?  I am interested in producing frequencies of at least 50-100 kHz.

Hey bentwookiee,

The myDAQ analog output hardware is capable of outputting 200 kS/s per channel.  Depending on the type of signal you want to generate the maximum output frequency will be something less than that, and I think the pre-built FGEN code supports a maximum frequency to 20KHz to ensure enough samples per period to generate a good signal.

Thanks!
