Well for about IEŁ600 (~US$700) you cauld get a handyscope, which is 2 x 25 Mhz channels with storage, combining to give a single 50Mhz channel (That's 50 Mhz on a single sweep - no aliasing). This thing substitutes a IEŁ2000 or so 'scope, a IEŁ5000 spectrum analyser and a IEŁ2000 data logger. It has unfortunately a very low top voltage The program options include multimeter and Spectrum Analyser.. For about IEŁ2200 (US$2500). you can get a full featured scope on a isa or pci card without this limitation, the equivelant of a 'scope beyond the range where I bother looking :-(. I already have the PB10 Eprom programmer - $110, and it does all standard Eproms, microcontrollers, and a bit more. That's an isa card. There are cheap Logic analysers, but I intend to go for one that lives with overvoltage, as I don't want it to spend it's life on my "IN" tray :-(. The version of the handyscope I had (It died when it was struck internally by lightning - DC Drive inline inductor, a s/c, and a blown fuse gave it BIG sparks) used Dos. Some have a windows version for the GUI and 'cos people have forgotten what DOS is. > > What does the luggable have to connect these things that a laptop doesn't? ISA SLOTS. Also, it may house a new m/b with pci slots.

I may have bigger promlems than that... -- Regards, Declan Moriarty Applied Researches - Ireland's Foremost Electronic Hardware Genius A Slightly Serious(TM) Company Experience is like a comb, that Life gives you - AFTER all your hair has fallen out! _______________________________________________ Linux-users mailing list Archives, Digests, etc at http://linux.nf/mailman/listinfo/linux-users
