  • Region overlap control for autorange/autoset functions
    Patent number: 8482564
    Abstract: A method of region overlap control for the display of a plurality of waveforms on an instrument includes an overlap function that allows selection by a user of a vertical height on a display screen for each of the waveforms. A ground marker for each of the waveforms is adjusted on the display screen according to the selected vertical height. The result is that the plurality of waveforms are displayed on the display screen in an overlapping fashion with sufficient vertical height to enhance triggering, all measurement functions and secondary functions, such as harmonics and switching loss measurements.
    Type: Grant
    Filed: October 31, 2007
    Date of Patent: July 9, 2013
    Assignee: Tektronix, Inc.

  • Indicia for Channels Collected Into a Group
    Publication number: 20080191894
    Abstract: An indicia for channels that are collected into a group has a head situated adjacent channel numbers representing the channels included within the group, and has a tail that encompasses the channel numbers. When the last channel in the group is selected, further turning of a Select knob in the same direction results in selection of the group, which selection is indicated by highlighting at least a portion of the indicia.
