    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.
     
  2. 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!

  3. 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.

    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.
