how to send signal if using USB-6009

[qinn]

Hi,

I'm curerntly using USB-6009 daq card. I want to generate sine wave signal in labview and send out the sine wave frequency via USB-6009 to a buzzer. How can I do that?

Regards,

Qin

Have you installed DAQmx? Have you looked at the DAQmx examples that are installed when you install DAQmx? There are examples that show you how to do that. You should also start here : Getting Started with NI-DAQmx: Main Page.

Please feel free to correct me if I am wrong. But as a heads up. I think the 6009 unit only support software timed analog output.

It does, but you can still generate a sine wave in LabVIEW and have the USB 6009 generate the analog signal. As long as the frequency isn't too high it should be feasible.

I  took a look in the specs and the max update rate is 150Hz. Perhaps a sound card (if available) is a better option. But both a sound card and the 6009 has limited current output. I do not think a buzzer can be driven by 6009 or a sound card. You will need some sort of amplifier in both cases.
