Title: advantest spectrum analyzer U3641
Post by: Ken121 on December 26, 2019, 04:52:18 am

I have a a
Advantest spectrum analyzer U3641 and don't know where to start on fixing it. I turn it on and it does one sweep. I think it just does that on startup. Does anyone know anything about spectrum analyzer repair and where I might start because I don't have a clue. Any guidance would be a wonderful, wonderful thing.
Thank you for taking the time to read this.

Start by putting a little more effort into describing what do you observe exactly and how is it different from what you expect. Perhaps, some pictures might help. Do you have a manual? Did you study some basic operation? Do you have schematics? Maybe a block diagram?
