Title: Setting maxacfrequency for PSS/PXF analyses
Post by n2sinha on May 1^st, 2013, 1:18am

Hello,

I am trying to simulate a switched-cap filter response using PXF. I am sweeping the frequency from 0 to 2.5MHz (my fundamental freq is 5MHz) and using 40 sidebands to see the filter response till about 200MHz. As per the spectreRF manual, I set the maxacfrequency in PSS to 500MHz [larger than (2.5M + 40*5M) = 202.5MHz] but I noticed that my filter response changes as I change this to 400MHz or 600MHz...

Can someone please help me understand how I need to set this "maxacfrequency" parameter in PSS and if I am missing something?

Thanks a lot! :)
