Might have been a mis-type...$2000 might be closer. I suppose if there are
$20K scopes out there, Wayne V. would have one. Being, he's gone on this
convention, he won't be able to back that.
If I needed to buy a $20K scope, it better do all the trouble shooting,
removal and solder of components, and probably spit out the Invoice.
Must be a Secore.;-)
BTW..not knocking Sencore..they have some good priority test equipment. But
too rich for my blood.
