Re: Difference between a 475 and a 475A
You're narrowly interpreting "inferior" to mean "slow", but there are other qualities to consider, such as overshoot, ringing, "dribble" and so on. If you allow a little extra overshoot, it's possible

Cool. That's something that I can verify! The scope whose faceplate reads "475A" does indeed lack a 2mV range (and it has a 100V range, which the 475s lack). That means that I should

Re: 465M Wave Forms
A EXT Trigger of the 460A to the A Gate of the 465M rear panel.
Probe on channel 1 input of the 460A then use it to poke around in the 465M

Re: Difference between a 475 and a 475A
Jeff,
My unresearched recollection is that the 475A was basically the same as the 475, but adjusted for higher bandwidth but perhaps slightly inferior pulse response. The 475A lacked the 2mV/div

Difference between a 475 and a 475A
I have a 475 that belonged to my father, manufactured in late 1974, that I have a sentimental attachment to and would like to keep running. To this end I have purchased several "for parts" scopes on

Re: Tektronix Technical Briefs (or whatever they're called in 2020)
These are a small fraction of the total number of Application Notes that were available from Tek. I accumulated this list because they have something to do with the 7000 Series of Scopes. This list

Hi Roy,
In the 1970s and 1980s they were known generically as Application Notes. Tek changed their numbering system several times for various reasons.
* In some cases they were published by the group

Tektronix Technical Briefs (or whatever they're called in 2020)
For several decades, Tektronix has released these "Technical Briefs:" a.k.a. Technical Documents, Application Notes, and possibly other names.
Is there a single point(s) of curation for them?
