Obscure Schlumberer scope - Looking for info and/or manuals
Hi All! First post here!
I got my hands on an early oscilloscope made by Schlumberger, the model number is 5602_C, allegedly a 100MHz digital scope from around 1985 with some advanced (for its time) math and analysis functions. My take is it was designed to be mostly controlled via GPIB.
The scope works fine, after some repairs to the power supply, but the absolute lack of documentation makes it difficult to understand what it can do, anybody has ever heard, used, repaired or has a service ad user manual for this unicorn of a scope stashed somewhere?
Usual sites don't have anything and the other handful of link I found turned out to be mostly scams.
I'd love to know more!
EDIT: I made a typo in the title, Schlumberger is not a word I'm used to type 😄
