Abstract: A digital oscilloscope comprises a sampling unit configured to sample an input signal received from an oscilloscope probe to produce a first stream of digital samples, a first acquisition system configured to store and process the stream of digital samples to produce a first data set, a second acquisition system configured to store and process the first stream of digital samples independent of the first acquisition system to produce a second data set, and a display system configured to concurrently display the first data set in a first format and the second data set in a second format different from the first format.

Abstract: A method for operating a data processing system having a touch enabled display screen that displays a plurality of waveforms to alter the display of one of the waveforms without altering the display of the remaining waveforms is disclosed. The method includes determining a selected waveform in response to a user touching the display screen in a first location thereby defining a touch area that determines the selected waveform. An operation that is to be performed on the selected waveform is then defined by a gesture on the screen. The selected waveform is determined by a touch area that is defined by the user touching the screen. If more than one waveform is defined by the touch area, the possible waveforms are sequentially selected until the correct one is presented to the user in response to the user repeating the touching that defines the touch area.

Abstract: An instrument and method for operating the same is disclosed. The instrument includes an input port for receiving a signal, a processor for measuring a first parameter related to the signal, and a touch-enabled display. The touch-enabled display receives commands directed to the processor and displays the first parameter. The commands including commands that determine how the first parameter is displayed and commands that determine the manner in which the instrument operates. The commands are grouped into a plurality of contexts. Each command in a context is specified by a control gesture on the touch-enabled display. A first control gesture is used for a first command in a first context, the first control gesture is also utilized for a second command in a second context, the first context being different from the second context.
