What you are showing is old tech which I also hated back when I used the earlier digital scopes trying to work on a peak tyrcking circuit I was developing for floppy diak analyzer systems. This crap does not happen on moderns scopes if you set them correctly (i.e. peak mode, and the correct sampling rate). A low cost Rigol, Siglent and even some Owon & Hantek would beat the crap of the HP digital you are showing! ...seriously man, please do not tarnish modern digitals with such old equipment from HP. I do still love analog scopes, just can't afford any these days. SHould have bought one back when people were virtually throwing them out, ..wanna get rid of your! :):):)
Hi Steven, You make a valid point. I'm comparing my "vintage" digital to clearly vintage analog. All my scopes are from the "sub $200" category and even that HP I have is a dinosaur by today's standards. There are certainly modern digital scopes which would easily outclass it and perform envelop detection without glitches. I've used very expensive present-day scopes which would perform these duties quite well. I wonder how well the "budget friendly" digital scopes would do though? Such as the $200-500 digital scopes on Amazon? I've read mixed reviews about them but I bet it's worth a try! When I was in school we had one EE lab with digital scopes, and they were truly atrocious even at the time. I believe they were made by Motorola but it could have been HP (it's hard to remember which amber-screen dinosaur is which sometimes). They were slow and clearly inadequate for most of their "digital" tasks. For example, enabling the RMS readout caused the display to move slowly and show only every tenth trigger. I hated them (we all did, the Tektronix analog scopes were so superior at the time!), and I suppose that is part of the bias for where this video comes from. Granted, the HP scope in the video does a reasonable job despite how ancient it is by today's standards. 73, --E de W6EL
Don't worry :) lots more videos on the way. I'll push a few short ones out, and in about a month or so we'll see some more interesting ones. See my channel page's "Videos" section if you want to check for more recent videos (and there is at least one).
You’re right, but I think you’re missing the point. My analog scope is ancient too. So here we have two old scopes. The digital one is a good bit more modern but they are both quite old. I use very fancy and sophisticated scopes at work all the time, but they cost more than a mortgage… if someone wants to make a rebuttal using *affordable* modern digital scopes I would honestly enjoy it and I hope someone does.
All but the cheapest digital scopes do that, "proper" digital scopes are 99% analog like. The HP you have there is garbage by todays standards, ...sorry!
The 54622A/D has digital phosphor. It can display modulation just like an analog scope. Still my daily driver today.
Is the decay time adjustable?

your digital scope is anchient, no offense, there has been a lot of progress made in the digital scope world today.
