Tektronix 5111A

[G7PSK]

I have seen a Tektronix 5111A Storage with 5A18, 5A22N and 5B1n plugins is this a good scope to have, I am not sure if it has cursors and readouts which is some thing I would like on the next scope I get, also what sort of money are they worth.

AFIK the 5A22N is the same as the 7A22 which is a very nice differential amplifier that goes to 10µV/div. Google the manual on the 5A22, I think you will be impressed.

As far as I can tel the scope is only 2Mhz band width I have 40 Mhz with the old National that I have at present or is the bandwidth set by the plugins.

Wow, I could not find any manuals for the 5xxx series

Lots of info here.

I also managed to download a pdf of the main instruction manual but for some reason it fails to upload onto the blog.

My apologies if you already saw this post of a 7A22 amplifier at 10µV/div measuring PS ripple.  These amps are only 1 MHz bandwidth anyhow.

I have one, and yes the manuals are as rare as rocking horse. Not the storage one, just the 5000 mainframe, and a 5A19 and 5B10 plugins. The 5A19 diff amp is a very nice plugin to use, you just do not have to worry about grounding issues at all with it as long as you keep in the CMRR limits. I want the 5CT1N plugin though, that will be very nice to get. Good for audio, and worked well on lower frequency digital devices.
