Synchronization of two signals

[dafemagu]

If I am reading two channels from the same device and I am using the same DAQ assistant to read it, the two signals are automatically synchronized or not? ,  Iam using a NI-USB 6009.

Good morning, Dafemagu,

The following are examples with synchronization. Any questions please contact us.

Thanks Marco,

I am acquiring signal like in the example 6009analoginput.vi, but for two channels and I want to know if the two signals are automatically synchronized or Do I have to do something extra?

I'm not sure what you mean by synchronized but if you mean simultaneous you should realize that the 6009 multiplexes its inputs into its ONE DAC chip so the two channels may be collected in quick sucession but will never be truly simultaneous.  If you want better control over the timing you'll have to graduate from the DAQ Assistant wizard and write real LabVIEW code which allows more control over the hardware.

thanks,

that is what I wanted to know.
