<good at looking at the color burst of a video signal in any detail. Again, <find most folks design/troubleshoot in a variety of areas and that's why w <need scopes with all the toys. I don't see Tek making any more 20Mhz boxes Two things. 465 is not a 20mhz scope though Tek made many slower ones. A 20mhz scope is fast enough to look at the main clock of an 8/e/f/m. I use it for faster stuff knowing it will smear a bit after all it is 20mhz at 3db... I can be a snob and buy a heavy gun, had one. The problem is the FEW times I need it I can borrow a nice 7400, or anything else that suits me. The rest of the time it would sit if I had it. For the bulk of what I do the B&K2120 is plenty good enough. If anything I'd consider a digital o-scope not for fast events but the painfully slow where the storage mode would be real nice. When you consider most of the systems I'm like to pull the scope out for are PDP-8, or z80(4mhz) speeds a scope better than 40-50mhz is wasted anyway. The fast stuff I play with really wants the 16 or more traces of the logic analyser anyway. I'd say this, buy what you can afford, newer is better. Best is if you can try it before you buy it. Buying used, if it's too old, good or not maintenance can be painful. I saw the writing on the wall with the 465, great scope but age is a potential problem for maintenance. Something newer will also stay calibrated longer too. Also for the electronically inexperienced servicing something like that can be more than a beginers project plus a distraction from the real task. Oh, the money I didn't spend on a scope was spent on other toys like RF sources and the like. Allison
