screen until the next trigger. Can analog scopes accomodate this?

sure it will not...
you can get quite cheaps digital scopes on ebay too...
but for that job you sure need a digital scope.

I am a little confused about digital storage oscilloscopes. I have
seen some DSO's that appear to have an analog screen (eg.
http://www.harlanlabs.com/2430a.jpg) whereas others are obviously
digital because of the LCD color display (eg.
http://www.testequity.com/Images/new/tektronix/tds2024.jpg).

I may be just mixed up, but can the first model (Tektronix 2430A)
acquire a 20ms transient, then hold it on the screen until the next
trigger, which may be a second later - or even hold it on the screen
indefinitely?
