Dear Forum,
My 1960s oscilloscope is finally getting a bit old & troublesome.
It's an S.E Labs SM111 which I have had since 1988, when I bought it from a test equipment dealer in Reading UK for £250. it's a fairly standard 18MHz dual trace, which I use for general purpose use for analogue & fairly slow digital/embedded micro projects.
It has another advantage of providing heat for my shed when I use it!
I want to replace it with something newer, but am not sure if I should go for a used Cathode Ray Oscilloscope (CRO) from a respected manufacturer such as Tektronix/Philips, or should i look at a newer type LCD model by one of the imported Hantek/Tekway/Rigol makes.
I have about £200 to spend. My requirements are dual channels as a minimum, although I can buy models with upto 4 channels. I think I should be aiming at about 100MHz bandwidth since I will be using it on PICS/Arduinos to about 20MHz.
On one hand I'm tempted towards a traditional type CRO, but cannot ignore the modern LCD ones.
But I have never heard of some of these manufacturers, so am worried about the risks of buying such. Therein lies my quandary!
It would appear that the modern LCDs specification would give much more capability; such as Spectrum/FFT Analysis, Logic Analysis etc. I've also seen some claims that extra bandwidth may be 'unlocked' by updating firmware, but this is not really a factor that would influence me greatly.
Any advice or suggestions would be greatly appreciated, as I can find discussion from both points of view.
Many thanks,
Simon B.
