Ok, I put this under EE because I wanted the opinions of how it will perform. I may be in the position shortly to specify a portable osciloscope for my use. It must be portable, so I am looking at the units offered by Fluke and Tektronix. I'm not really including the TDS200 etc. series by Tek. I know these units have LCD screens, so they won't be the same as a real CRO. I'm looking for a scope to help with my PIC work. I hope to be moving to the 40MHz 18f chips soon, so that should give you an idea of the speeds I am working with. What do people think of the Fluke 123? I know it only has 20MHz bandwidth, but I liked the extended voltage ratings. Failing that, how about the Scopemeter 192 or 196? A page with a comparison of them all is at: http://www.fluke.com/SCOPEMETER/SELECTION_TABLE.ASP?NEWTARGET=FALSE?AGID=6&SID=14 I guess my basic question is, which unit would be the best for digital troubleshooting, letting me view waveforms and communications and the like.
