any pointers for buying a low cost oscilloscope for hobbyist tinkering
of tv/vcr etc
like what freq/voltage ranges generally to look out for.
are the pc based or handheld LCD ones any good?
thanks
Gee, oscilloscopes are like cars ... you will get hundreds of opinions ...
all valid perhaps but all focused on user bias.
If you have never owned one before, start very basic and start used. For
example, there are flea markets called "hamfests" where you can sometimes
pick one up from someone local who cannot screw you as you "know where he
lives." Ebay is rife with them but be wary!
Stay away from digital scopes and high price tags until you get your feet
wet with an older analog scope.
Bandwidth of 50MHz should be good, dual trace, 20 mV sensitivity. Tektronix
is the best brand name out there, by the way.
