Instrument having a virtual magnifying glass for displaying magnified portions of a signal waveform

摘要: An electronic instrument which has a virtual magnifying symbol capable of portion the instrument's signal waveform in single window display. The user is able to position with knobs, buttons, or, more preferably, pointer, such as mouse, digital pen, or touch screen. can be employed at all times during display waveform. In preferred embodiment, glass. centers desired within lens glass, then magnifies portion. Thus glass present invention provides an innovative solution for simultaneously context entire Viewing, waveform, that allows operate efficiently and accurately.
