A drop in fixed ferquency alias filter product for inside BNC-2090A?

[bradh]

The BNC-2090A allows for addition signal conditioing to be added internally.  I have a high channel count and we run at fixed sample rates.  I would like to buy "drop-in" fixed frequency alias filters (hopefully active filters).  I would do it with passive networks, but then I have to deal with calibration.  Due to our high channel count, I would like to just purchase something that comes calibrated.

bradh,

What kind of signal are you measuring and what type of filter are you looking for?

National Instruments does not offer any "drop-in" components.  If we know what you are looking for we can try to help you build the circuit you need with the 2090, but that sounds like it is not an option for your system.

I am looking to just build an active low pass anti-alias filter (i.e. bessel).  while I can build up a circuit for myself, I will have to calibrate the circuit.  To do this on a large channel count system, becomes tediuos work.  So I was wondering if anyone knew of a drop in product.

bradh,

I know you mentioned high channel count, but if you are looking for a drop-in bessel type module you might want to take a look at the SCXI-1142.  I hope this helps please feel free to ask any questions you have about this module or otherwise.
