Some of the more expensive DSOs even have color displays. Scopes with color displays allow you to program the color of each trace, making it easier to find the trace you're seeking. Since some scopes have up to eleven displays, color displays are almost a necessity. DSOs not only make the job of the user easier, they also make the calibration technician's job much easier. Calibration techs no longer have to tear down an instrument to tweak a bunch of potentiometers.
Calibration is quite automatic, too.
A tech simply connects the instrument to a computer-controlled calibrator, which communicates with the instrument's processor through a serial link. The calibrator controls the entire process, performing an entire calibration in about a quarter of the time it would take to calibrate manually. Automatic calibration also produces any reports necessary for your quality certification program. The probes furnished with today's scopes are also easier to use than their predecessors. If, for example, a user plugs in a current probe, the scope will recognize this, change the units on the display to amps instead of volts, and do any scaling required automatically.
