Oscilloscope recommendations
I've been in the TV business 26 yrs and am still using a 1979 model
scope 30mhz Leader. Is there a big advantage to these new digital scopes? I've also got a Fluke 123 scopemeter that's 20mhz that I'm not thrilled with. Any recommendations for a TV guy who also dabbles in pinball repair that uses digital timing on ICs. I can't make any sense of any digital signals with the old scope or the Fluke. |
Good advice. I picked up one of these in that $ range a while back and it
is a great scope other than needing a lift to move it. There are tons of these out there and mopules are cheap. Leonard "Dr. Anton T.

Based on your stated applications, you could get a heck of a lot of performance out of one of the older Tektronix 7000 series instruments. I would suggest a 7603 mainframe, a 7B53 timebase, and a 7A26 vertical plug-in. All should be available from ham swap meets or greed- bay at pretty reasonable prices. In fact, I'd be surprised if the whole thing cost you more than $100-$150. This setup will be good from DC to at least 100MHz. If you need higher bandwidth to grow with as your needs change, I would suggest a 7704 (250MHz), 7904 (500MHz), or (if you really need gigahertz bandwidth) a 7104 mainframe, coupled with appropriate plug- ins. If you would like something 'luggable,' yet versatile, I would suggest a 465 or 475 series portable 'scope, preferably with the multimeter option. You may also want to look into a 7D20 digitizer. They were practically made for the 7603. Happy hunting. Don't forget decent probes! -- Dr. Anton T. Squeegee, Director, Dutch Surrealist Plumbing Institute.

Thanks for the recommendations guys. These look pretty good. Any
thoughts on the new lower end Tektonics like the TDS2014 which is a 4 challel 100mhz color digital scope? About $2000, i was a thinkin. Thanks. |
