I don't know why, but I just happen to have a 8553B manual on my desk.
The UNCAL light (according to the parts list) is 12V 0.06A. The wiring
to it comes from the Bandwidth & Scan width switches via the IF section
(which I don't have a manual for). It is very very complicated! (I lost
count of the number of manual pages it covered;-)

Ps: Wish I had the analyser, not just one of he manuals.
