Clyde try the HP 3550 (I think) its a twochannel scope and a 16 channel logic
analyser all in one (Going to try and get one in next years budget) its about
£3500 but well worth every penny I have hired one in the past to fix nasty
problem its a verry nice pice of kit and does exactly what it says on the
box.......

Cheers Steve.......
