SCXI 1125 lowpass filter

[Padeanu.L]

Hello I am using a SCXI 1000 chase with two SCXI 1125 cards. My question is how can I configure a software filter that works like the one implemented in the SCXI 1125 card. More exactly i what to build a 4 Hz cuttoff lowpass filter. Thank you.

Hi Padeanu.L,

What is keeping you from simply configuring the Voltage task to use the built-in 4Hz filter (shown in your screenshot)?  Are you trying to implement this filter using lower-level VIs, or is there other hardware that you want to add a filter to?

I am using another acquisition card that does not have this option!

Which module are you using?

I suppose you could always just run your signal through the Filter express VI (in the Express » Signal Analysis palette) or one of the VIs on the Signal Processing » Filters palette.
