Portable units sport impressive GUIs, or lack them altogether

摘要

Think handheld instrument and you might envision a 31/2-digit display and a large knob you can manipulate while wearing heavy-duty work gloves. But portable instruments making news recently are sporting impressive graphical user interfaces-if they embody a user interface at all. Instruments with user interfaces include the R&S Cable Rider ZPH cable and antenna analyzer, which includes a color touchscreen with familiar smartphone-like operation. Users can place markers simply by double-tapping signals on the display. The analyzer also can be operated via the extra-large, widely spaced keys that allow easy handling even when the user wears gloves.
