Focus on: Scope multimeters

A new type of test instrument, the portable digital storage oscilloscope (OSO) has appeared on the electronics scene, and looks here to stay. This instrument is often combined with a digital multimeter (OMM), and is marked by a large LED screen and a control panel which make it particularly suitable for field use. Prices of these units are beginning to come down to a level where even the hobbyist may become interested.
