Hi Andrasoni,

Looks like a scope with a CRT - China does lcd scopes with bells and whistles that you can pop into a pocket - colour display too - Got mine for 50 Quid - Chris.

Hi Andrasoni,

Guess you're probably right - When I had tubed versions on the bench, used 'em most every day, but now having a pocket size solid state device that possibly does wonders in colour, it stays in the drawer, as I can't bother spend the time working out what it does with it's minimal sequential buttons.

At least with a CRO you know where you are, with a switch for every option - Chris.
