Tektronix 7613 Oscilloscope with 7L13 Plug-in

Check out http://www.caip.rutgers.edu/~kahrs/testeq/7000.html for a great list of plugins and descriptions.

I bought this one with a 7L13 spectrum analyzer in it, but eneded up buying a 7934 with other modules I wanted in it, so I don't need the mainframe anymore.

All functions appear to work properly. But, I have not checked it against all specifications and can not guarantee calibration. The chassis has a few minor scratches, but all the control knobs are functional and the interior is extremely clean (see photos).
