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.




One of the least expensive used TEK scopes would be the T932/35,35 MHz
BW,not having any TEK-made ICs in it,and easily serviceable.
One of the simplest scopes TEK ever made.

Or the TEK 442,a rack-mount version of the T935.

(T932=single channel vertical,T935=2 chan.)

Next on my short list would be the TEK 2213/15/35 series.(incl. "A"
versions)

(not 2230/32 digital models)
