anti-alias filtering

[gjlb]

I am looking for a suitable daq system. The new CompactDAQ NI 9205 looks good, but I am wondering about anti-alias filtering for this card (or other new NI cards). I remember having read somewhere that new cards (M-series) do anti-alias filtering on-board, but now I can't find any information about this.

Is it true that the card above does anti-alias filtering for each valid sampling rate ? Or do I need a separate filter?

All the best, Gabriel

In the table on this webpage you can see which modules hava a aliasing filter:

The 9205 has none.

The modules that have one will have different filters. Please check the specifications to see which filters the single modules have.

Concerning the M-Series boards, only some M-Series boards have a filter:
