Hello Folks,
Question: It seems that most portable DSOs in the 200MHz/1GSPS class
don't offer delayed trigger anymore which makes pulse-echo measurements
a real pain. Why don't they?
After all it's just a simple counter that is needed. Same for hold-off
which typically ain't there either :-(
Beats me but IIRC I used delayed trigger on a lower end TDS220 although
its data sheet said that it could not do it. However, that scope had
some other serious issues (noise) so I asked the client to obtain a used
2265. Old Faithful, of course, always has delayed trigger but sure
enough the plastic clutch for that function fell apart right away.
Designing a trigger delay into an analog scope is no small feat but for
a DSO it should be really easy.
