Tektronix 5L4N 0 to 100 kHz Spectrum Analyzer Plug in for 5000 series scopes

from Tek 1977 catalog pg 194: "The 5L4N is a 0- to 100-kHz spectrum analyzer that offers both high performance and economy. The analyzer features selectable input impedances, 80dB of dynamic range, and a built in tracking generator"

I tried this when I got it in the recommended 5111 scope and got it to work but I haven't tried it recently. No test notes.

The broken tab is a problem. I didn't break it! Getting access to release the plug in from the scope should be considered (remove the bottom scope cover?), or removing or replacing the tab. I think with this style, you need to remove the front panel?

If you need this to complete your collection or just want to play with it, here is a nice example 5L4N.

Untested.

Includes an original complete manual (operating and service) about 1/2 inch of paper.
