Arif,

I use an Agilent 54622D Mixed Signal 'scope. It has simultaneous sampling of two analog and 16 digital channels at 200 MSamples/sec. It has many of the niceties such as X-Y display mode, save setup and trace data to a floppy, a horizontal channel that goes from 5 ns/div to 50 s/div. It's great for micro and analog work. Best of all I picked it up reconditioned for $4100.
