Tek 2230 @ 2232

Hi; Question to you Tek gurus; is the 2230 a true digital scope meaning that what you see is a digitized signal or is it an analog scope that has a digital storage function that you turn ON whenever you need to capture something ?. Is the 2232 the same in that respect ? . I remember using one of them years ago at work - I could see a nice trace of 67 MHz (analog) but I could also use a digital storage function to capture a 20 kHz event. Now I need one for myself; as for the digital scopes I've found that the ones I'd accept are those with 2 Gs/sec to be able to see a series of not very repeatable periods at 80 MHz but they are a bit too expensive... .So I need a 100 MHz analog with digital storage capability at lower freq.
