etc.

I don't immediately see a File folder for the 7J20 in the Files section.
Does such exist ?
Are copies of the manuals, etc. in there ?

Thank you. The papers published in Applied Optics appear to be behind a
firewall. But I see that the first paper is co-authored by Jay Pasaschoff
whose textbooks on astronomy we hsed in college.

A .pdf of the 1976 Applied Optics 7J20 paper was randomly uploaded to the Files section.

-- Who in this group still has a Tek 7J20 RSS ?

-- Is anyone familiar with the differences / similarities of the Tek 7J20 vs.
the Hp 70k 70950a / 70951a / 70952a series ?

I have a 7J20/J20. I haven't used it in a while. It's on my "to do" list.
But I am grateful when I run across application notes for it.
