CHECK OUT THE WIKI The purpose of the wiki is mainly to allow you to find information on instruments, either from either
- The model number
- The function(s) listed below. Some instruments have multiple functions - for example, the 4195A is a VNA, spectrum analyzer and an impedance analyzer. Therefore the 4195A is listed in multiple categories

Re: HP 1727A CRO: Problem with the vertical output amplifier.
-------- These voltages look pretty much on target. Take a look at the voltages on 1725A schematic that uses the same ICs. I agree it is an interesting choice to back feed +15V supply. It saves some

Yes, one can set any limit on attachments, even including a size of zero so you don't get any. i believe that groups.io will compress images to a size you set too, although I am unsure of that.
