I am awaiting my Microtest cable scanner.  This paragraph in the brochure
convinced me to buy it:

"Connected to an oscilloscope, Scanner's precision, high-speed, pulse-
generating circuitry offers installers and other technicians a detailed
view of the entire LAN, including transceiver, terminator, and multiple faults.
In other words, you get the capabilities of sophisticated time domain reflec-
tometers.  But not the expensive price tag."

Anyone tried this?  Does it work as advertised?
