Did these CRT-based digital scopes have fully rasterized graphics for the plot or do they somehow use an analogue sweep?

- wrs 6y agoThe former, I’m pretty sure. I’ve never heard of a “hybrid” display on a digital scope. Interestingly, though, there are sometimes deliberate simulations of analog behaviors on the digital display.

- wrs 6y agoYeah, those are cool! I do seem to remember analog scopes with auxiliary digital displays on the screen for measurements. But not the other way around, digital samples displayed with a vector CRT beam.
- gaze 6y agoThere’s an HP spectrum analyzer that does this.
- tverbeure 6y agoThere are bunch of Tek scopes of the era (the TDS 700 series etc) for which you can buy kits that replace the CRT screen by an LCD panel.
