Original poster: "by way of Terry Fritz <twftesla-at-qwest-dot-net>" <Mddeming-at-aol-dot-com> Hi Tek-ers, I am looking at a device for sale called a TEK 1480 R Waveform Monitor. From the pictures, it appears to possibly be some sort of CRT from a modular tektronics system. Anyone have info on what it is, how it differs from an o-scope, TC usefulness, etc.? Matt D.
