Hi There,
We have a scope at work with 80SJNB - I'll check to see if I have on CD - however it's pretty old (Windows 98).
Also, you can download 80SJNB for Windows XP scopes from the Tek website.
Which O/S is your scope running?
However, getting the software is just part of your challenge. You will also need a license code -> Google is your friend ;-)
Regards,
- Guy.
