Hameg in EU can be found for 5..100€ 10..100 MHz have several in Paris


Best scopes are Tektronix 465/475/B, 22xx series and 2465B, 2467B.

I have a Tek 465B that I've had for many years, it's a great instrument and I have no plans to part with it, but frankly I rarely ever use it anymore since I have a newer DSO. The CRO is as someone else mentioned, a lot like a classic car. It spends most of its time in storage but I pull it out now and then for some nostalgia or when I have a specific need such as XY mode that it does better than any DSO. These days I only recommend analog scopes to beginners if it's very cheap and the only scope they can afford. Even the newest analog scopes one is likely to find now are decades old.

IMHO one of the $50 pocket scopes from Aliexpress is a better buy compared to any analog scope unless you are desperate for bandwidth. My first oscilloscope was a 20MHz one which costed US$900 in today's money. Even one of the $50 pocket scopes runs circles around it. Most annoying to me was the inability to visualise low frequency signals.

Now it's a sinking ship.

Tektronix was dominating the market when analog scopes were cutting edge. HP/Agilent/Keysight and Lecroy started eating their lunch with much more advanced digital scopes in the nineties, long before Rigol scopes become known in the west.

Now Tektronix appears to be catching up, and their latest models are getting decent reviews. Obviously they are not aiming to compete in the sub-$1000 price bracket. So I'd argue reports of their demise are greatly exaggerated.

Like all other "Global Players", because they simply don´t need it.
And yes, the last 10yrs were a technical revolution for hobbyists to get cheap but usable DSOs.
But there are still differences between "cheap" and the rest, there are features for example our very old lecroys got, new scopes won´t have.
Until you pay for them as much as the old lecroy had cost 25yrs ago.
And the enthusiasm goes so far that people complain when a scope for 400 euros can't do everything that a scope for 20 times the price can, which I find sometimes very funny to read.. ;)

Not quite true. Tektronix' TDS210 / TDS220 where real game changers that put 1Gs/s realtime sampling scopes on the desk of electronics engineers as a true replacement of analog oscilloscopes. And designed to a low price point as well. The whole board is like the size of 2 credit cards. I have not seen any of the low cost Chinese brands achieve such high levels of integration.

Agreed. Tektronix still knows how to make good oscilloscopes. And they are not the only ones who have been milking old architectures.

With a modern digital scope, you get an accurate frequency counter and time interval meter built in, and on-screen display of time and voltage values without having to count divisions on the screen.
