All my scopes are analogue. Got 4 now, I think. May have forgotten one hiding somewhere. This is my escape from the digital world of the day job which basically involves wrangling all things software, a loveless pit of hell perfectly described here:
https://www.stilldrinking.org/programming-sucksI like the warmth of "proper electronics", the sheer engineering beauty and the Apolla era design ethic which seemed to have faded out in the 1990s in favour of shitty bits of plastic stuck together by the lowest bidder and crammed full of black box abstractions. On top of that the analogue stuff is possible for a human to truly understand in a lifetime and become at one with. When I say at one, I mean be really close the fundamental abstraction of the universe. You can visualise the holes and the electrons moving around and can see WHY there a ground plane fizzing away. You can look at the board and see what the designer intended. I can understand why the likes of Williams, Widlar and Pease did their thing and enjoyed it. If only I was born years ago.
I'm impressed with this 475. I've had a few 465B's (and still have two, both knackered). My current daily driver is a Philips PM3217 which is generally a really nice scope but at the high end of the bandwidth turns to dog cack in the triggering department. This 475 is triggering quite happily at 230MHz on a -30dBm signal terminated at 50R when connected to my Marconi 2019A which is to be honest, bloody mental! Also has a 2mV/div sensitivity in the Y amplifier
Scarily enough as well, this has crow's feet all over it (so UK MoD ownership) and the last cal date was in 1984 and the thing is still spot on according to my counter and voltage reference. Good job Tektronix!
It's currently hooked up to my HP3312A measuring rise time which is in spec at 14ns, while I can hear the gentle and quiet soothing whirr of the fan inside and the periodic clicking of the thermostat in my TCP iron! I love this
Edit: now on eBay looking for a new frequency counter
