Hi Claudio, I had a 5372A a while ago. This is from memory and old email. Won't guarantee accuracy!
I was given an FFT card with option 040 in ROM. So yes… a firmware option... Not an option that you could simply load or enable. I also remember being instructed to copy down the calibration values from the 5372A and to re-load those values if changing out the FFT board... I would not want to lose calibration if I ever went back to the non-option 040 card. I kept the calibration values saved on paper and stored with my 5372A documentation. There’s a good chance this is correct, but can’t promise… 5372A and all my documentation went to a good new home some years ago. Anyone else have a less fuzzy memory, or better still, does anyone actually KNOW?

Do any of you have information about it?
