Antialias DAQ 6210

I'm using a DAQ 6210 to take measurements from sweeped measurements from a device. If I sweep, say, 0-200Hz, I notice in the spectrograms of my data that there are high-frequency components that are contaminating my data. 

 

I think this contamination is aliasing, and of course I'd like to avoid it.  

 

Long story short: do the 6210 DAQs have a built-in antialiasing filter? If not, do any of the other NI DAQs have this feature?

 

 

Thanks!

Hi ap8888,

 

We actually have an entire product line that include anti-aliasing filters and a different acquisition method that you may want to look into.  They are our DSA modules.  In terms of DAQ devices with this functionality with have the USB 9229 and 9239.
