if it's for audio a 20mhz dual beam analogue scope will do.
if it's for rf then a 300mhz scope will fit the bill.
if it's for digital signals or intermittent signal capture then it's got to
be a digital the more the sample rate the better.
I use a tektronix 2211 it's the best of both worlds it has a fairly high
sample rate and a medium wide bandwidth, it's both analogue and digital on a
crt and not tft.
Best of all it only cost £300.
I have also the latest digital 4 channel tek scope mega high sample rate,
tft, floppy drive, printer port, ethernet and serial comms, all the biz,
it's on loan however.
Give me the 2211 anyday, it's far easier to drive, with the new tek it took
ages to get round all the buttons.
