Shopping for an oscilloscope. Talking to one of my tool dealers, he's got a used 2 channel digital scope with about a 6" screen for $1,000.
Looking on line and thinking why not just piggy-back on the laptop? Found this scope online. So you would have a 15" screen 2 channel digital scope new for $350.
Here's the specs, questions, how does this thing have 2 channels with only one external trigger input?
would this unit's specs work with a programmable EFI GT40?
