Aspect ratio of oscilloscope displays
Renate:
In ye (really) olde days, oscilloscopes had round CRTs.
Then they got a bit squarer, then a bit rectangularer.
A lot of LCD display scopes today seem to be 4:3 or so.
That might be a good aspect ratio for eye diagrams or sine waves.
Still, if you're looking at some sort of data stream, I'd prefer something wider.
So, what do you think? Do you care? Would you want a scope with a wider display?
Does anybody try to sell a scope with the display as wide as the (landscape style) chassis?
Benta:
In that case, use a USB scope and let your PC do the rendering.

Todays scopes follow the trend of more or less cheaply available display sizes. So one can expect a new scope to have a 16:10 or 16:9 screen today anyway. Smartphone displays may be wider, but a scope manufacturer wouldn't use them because they're usually as quickly phased out as they appear due to rapid model changes.

In point of fact, that's what I do, using custom software.

Yes, but many current scopes have a wide screen already. E.g Rigol DS2000 and MSO5000 both have roughly 16:10 aspect ratio.

Yes, e.g. LeCroy LabMaster 10-100zi or the Tektronix 5 Series. I don't recommend looking them up though, the prices are not for the faint of heart.
Anyway, I personally like real separate controls for most everything on a workhorse scope.
