PXI-4071 Feature: DC Noise Rejection. Different between modes ?

[MaxiMuz1979]

Hello everyone!

 DC Noise Rejection has 3 mode (Normal, second-order, high-order). In the description described that all of they are differing the relative  weighting. And shown the graphic with relative weighting vs t_aperture.

What does mean this graphics ?

How is voltage calculated ?

Hi MaxiMuz,

The relative weighting vs aperture graph shows how over a time length of t_aperture what each sample the weight of obtained will be. I am assuming you are talking about this document:

You can think of the relative weight as a multiplier. For example in the high-order plot if a sample is taken near t=0 then the samples value will be multiplied by the relative weight at that time (which is close to zero), where as a sample taken at t_aperture/2 will be multiplied by 1 which causes it to have much more of a weight than the previous sample.

Thanks for answer! You clarified situation.
