Hey, For the math channel, I can't find in the documentation what the 'custom filter window co-efficients' are exactly - is this like a FIR/IIR biquad filter? I am testing a phono pre-amp with square waves, and trying to filter the AD2 input channel with an inverse RIAA EQ curve. I can find numerous FIR/IIR biquads to achieve this but unclear what values I enter in the custom filter as window co-efficients. Alternatively I could filter the square wave output produced by the AWG with the RIAA EQ curve but can't find a way to implement that either. Many thanks David
