I've just recently repaired a Tek TDS7404 scope with options 4M, J1, and J2. The disk drive was a total loss, so after rebuilding it, I am missing option J1 which is TDSJIT2 Jitter Analysis application. The software is not on Tek's site and I'm hoping someone here may have a copy. As of now, it also shows option J2 missing (TDSDDM2 Disk Drive Measurements application) which I do have a copy of but don't need.
If anyone has a copy they could share, I'd be very grateful. In the meantime, I'll send an email to Tektronix support to see if they can help out.
Thanks!
Jay
