The tube scopes...5XX series that had interchangable verticle modules had several modules available that could read down in the uv region.... I think one would have to put at least two 7A26's which are good down to 5 mv in series to be able to do that.
The 1A1 had a sensitivity of 500uv and there are also differential input modules with similar sensitivities.

the differential amplifiers for the 7000 and 5000 series scopes will get down to 10uV/division -- and you can bandpass limit the response.

I believe that the TEK 1A7 differential will do exactly the same thing. Of course on HAS to have a screen room or be well underground in order to read anything accurately at that low of level.

I picked up a nice-mint 564B Storage Scope yesterday for 40 bucks. In like new condition it is an ex-BYU Physics scope so probably does not have tons of hours on it as an industrial lab scope normally would. All tubes test good and it works perfectly. Sure, its only 15mhz but its dual flood gun type storage crt has a trace as sharp as a regular scope does... much sharper than my 7633 mesh type storage scope has.

I have alot(over 20) of both TEK solid state and tube scopes and the tube scopes are still the better performing of the lot.

if you note the Linear Technology website application notes -- Jim Williams uses a TEK tube scope for his noise measurements.

I went to rent the Faraday-Shielded room at my alma mater in NYC -- regrettably they had taken it apart. I now have a setup with brass screens retrieved from the dumpster. I think that when you see an amplifier with THD approaching 0.0004%, or the noise measurements in the pico-volts they have made the measurement in a shielded environment.

OK,

I see that one of the vert amps for the 7000 uses powered probes. Anybody know about this?

He is most likely using the 1A7 diifferential amp to do this since it has the lowest noise floor of all the tube based plig ins. I am in the process of cleaning one up (Ultrasonically) that I just bought on E-Bay. I also picked up a 1L20 Spectrum analyzer but have not received it as of yet... this is a VERY rare TEK piece!

I received my 1L20 spectrum analyzer plug-in the other day. This is a really neat piece and a very rare one at that.
