Re: No one going to chime in on the TAS485?

There is a free operation/service (to module level only) manual on Tek website.? You have to register for access.? I think this is a module repair only type scope like most of the TDS series.? There was a mention somewhere of a component service manual for one of the TDS series.? Tek does keep a fair number of manuals on their site.? Find the search for manuals and search for the TAS485.
Rolling your own amp is certainly possible.? e.g. http://www.analog.com/en/high-speed-op-amps/high-speed-differential-amplifiers/ada4950-1/products/product.html? Note that a cheap evaluation board is available as well.

I'm leaning more toward the 7000 series. I just haven't found out much about the TAS series. I'm worried that, being about the last of the analog scopes, that they might have a lot of custom parts. Besides, a 7000 series with 7A24 or 7A26 plugins will do what we need and be repairable too.
