USB-6211 w/ DAQmx

[bonnerupc]

Greetings All,

Requesting if any user can verify that the DAQmx; Channel Properties Node; Filter; Window Averaging function is supported by the NI USB-6211 OEM board?

This functionality is critical for the planned app and need to know before ordering.

Thanks Group,

Chris

Hi Chris,

No, it is not. AI.AveragingWinSize was added for a specific use case that requires some signal processing to be done in hardware: NI-DAQmx Hardware-Timed Single Point Support for Oversample Clock Timed Devices

For more general use, LabVIEW has a wide variety of signal processing VIs, such as for windowing, FFT spectrum (with window), etc.

Thank you Brad_K, By 'no it is not' I assume you mean that it may not be what I need. You make this assertion although you do not know anything general or specific about my application needs :>( If I misunderstood your comment please correct me. That being said, it does appear that the function in question is suited for specific NI hardware w/ overclocking capabilities and functionality - generally PXI devices (as per write-up you provided). I have not used DAQmx that much and am somewhat confused as to what will 'work' with the basic functionality of the mx subroutines and specific setting alterations. I know I can 'filter' the functionality I see for installed hardware, but IMHO that hinders learning what the vi's can 'do'. I believe the zero-phase IIR filter may provide the particular smoothing we need, but results may vary so-to-speak. Thank you for your response, Chris

I wrote "No, it is not" as a reply to your question. I should have written, "No, the AI.AveragingWinSize property is not supported by the NI USB-6211 OEM board."
