I don't know if there is a test equipment list or not but here goes
anyway.

I've got a brand New in the box Tektronik "Termination for P-6016
Current probe".  I don't see anything like that listed on the Tektronix
website.  Anyone have any info on it or what it might be worth?
Paperwork with it only shows parts breakdown with no other info.

It has a BNC female on one end and a PL-259 on the other.  Slide switch
on one side.  

Thanks for all the info in advance.
