Vintage HP 8015A Pulse Generator

Description

This is in excellent cosmetic condition, but I am not sure if it is fully functional
I was able to get pulses, the Vernier controls work fine, and the leading and trailing edge controls seem to work OK.  See Photo 5 where I adjusted the leading and trailing edges to the pulse shown in Photo 4
I do not know if there are problems elsewhere in the 8015A as I don't have a manual, I'm not familiar with the 8015A, and my scope is limited in bandwidth.  This almost 50-year old unit is sold AS IS and there is NO RETURN, so be sure this is what you want and ask questions before bidding.
