Hello,

Hopefully Andrew Beckett will see this post and add shed some light on this issue...  :)

I'm trying to simulate some ADSL circuits (i.e. >90dB linearity specs) , and I've found that I get VERY different results for when I have the output file in psf format vs. sst2 format. In short, the psf output looks good (~95dB linearity), but the exact same sim in sst2 format is garbage, with only ~40dB linearity.

I'm running a transient sim in conservative mode with default tolerances. I've also specified a strobeperiod so that the dft function has "real" data at the sampling points.

Any explanation as to why sst2 output gives lousy results? Is there any way to make sst2 output better? If not, is there a way to force output to psf?

Thanks much!
David
