My favorite feature is writing speed.
We have one hooked to a network analyser, ploting color traces of cell tower
antenna impedances. Although the 7550 is not easilly portable, niether is
the Network Analyser. But you have many colors to discern different
antennae feedlines and the completed plots expedite proof of performance
reports. Storing traces to diskette might be an option, but it's still
slower printing to color inkjet back at the office. You can also more
quickly mark up the plots to keep them straight, rather than having to give
each file a descriptive filename on diskette.
