Hey, HEY, just what are you trying to say, huh?? But seriously, I need to remove that wallpaper, just been procrastinating. It's leftover from the previous owner of the house, and they had very poor taste in wallpaper. I have not yet calibrated the 8903, just the 8175. The 8903 seems to be pretty close, and looping it back into itself with a 1KHz @ 1V signal and the 80KHz low pass on gives me a reading of around .002% distortion. I can get it to about .0014% with the overhead lamp off. Not too shabby.
