ProPlus (Celestry) 9812B Noise Analyser User Manual

[tec5c]

Hi all,

I have bought a Celestry (now known as ProPlus) 9812B 1/f noise analyser online however all efforts at finding any documentation on this bit of equipment have resulted in nothing. Even though this bit of gear has been superseded by the 9812D and just recently the 9812DX I still cannot find a user manual for any revision.

I have looked all over the internet, contacted ProPlus (no response) and yet still nothing. This line of equipment is claimed to be the golden standard in the industry, so one would think that there would be some documentation available?

If anyone has a copy or knows of where I could locate one then I would be most appreciative. Even if you have experience with this bit of gear, I'd love to pick your brain.
