Hello all!
I'm planning on buying an analog oscilloscope. I already have an Agilent MSO-X 2014A, great scope, but sometimes I feel like/need using a good old analog scope. And for looking at signals in XY (e.g. vector graphics), nothing beats an analog scope.
The Tektronix scopes that I currently find most interesting are:
2225: Seems small and simple to repair as there are no cursors or other option. 500uV/div can come handy.
- Difficult to find in Japan, only one found so far. It has some problems with noise from power supply and controls.
2236: Seems like a cool scope, with DMM and counter.
- Also difficult to find. On the one I found the DMM seems to work but no information on the scope function itself..
2465A/B: State of the art! High bandwidth. As someone in another thread said, probably the best analog scope ever made.
- There are plenty, today there are 5 on sale. Here I have two options
I: Buy a refurbished one with free repair warranty, with GPIB and Counter options, and one probe. Cost is about $600.
II: Buy 3~4 for totally $100 and make one that's working. (probably the most fun option but as I'm living in Japan, space for gear is very limited.. and the wife might get upset by all that "junk")
Anyone have any advise on these scopes? I would like to know where I can get the service manuals and spare parts.
Thanks!
