Abstract

A method and test system are provided for selectively emphasizing waveforms on a display of the test system. The method includes presenting a graphical user interface (GUI) on the display of the test system; receiving through the GUI a selection of channels to be viewed on the display; receiving through the GUI an indication enabling a waveform emphasis feature; receiving through the GUI an indication of a cycle time; and displaying through the GUI multiple waveforms, respectively produced by the selected channels, by sequentially emphasizing each waveform of the multiple waveforms for the cycle time as a viewable waveform, while de-emphasizing each remaining waveforms of the multiple waveforms in relation to the emphasized waveform for the cycle time.

First claim

The invention claimed is:

1. A method of selectively emphasizing waveforms on a display of a test system, the method comprising:
presenting a graphical user interface (GUI) on the display of the test system;
providing a plurality of graphical elements in the GUI corresponding to a plurality of available channels for receiving a selection of a plurality of select channels from the plurality of available channels to be viewed on the display;
providing a waveform emphasis graphical element in the GUI for receiving an indication enabling a waveform emphasis feature;
providing a time graphical element in the GUI for receiving an indication of a cycle time;
providing a plurality of display format graphical elements in the GUI corresponding to a plurality of available display formats for receiving a selection of a select display format from the plurality of available display formats in which a plurality of waveforms, respectively produced by the plurality of select channels, are displayable on the display; and
when the waveform emphasis feature is enabled, displaying through the GUI the plurality of waveforms from the select channels in the select display format by sequentially emphasizing each waveform of the plurality of waveforms for the cycle time as a viewable waveform, while de-emphasizing each remaining waveform of the plurality of waveforms in relation to the emphasized waveform for the cycle time,
wherein the plurality of available display formats comprises at least an overlay waveforms display format in which the plurality of waveforms are shown simultaneously in a single window on a same grid and at least one individual display format in which the plurality of waveforms are displayed simultaneously in a single window on corresponding separate grids, respectively.

2. The method of claim 1 , wherein the plurality of available display formats further comprises a windows display format in which the plurality of waveforms are shown in a corresponding plurality of windows, and
wherein sequentially emphasizing each waveform in the windows display format comprises sequentially positioning each window of the plurality of windows in a foreground of the display for the cycle time, such that the corresponding waveform is displayed as the viewable waveform, while positioning each remaining window of the plurality of windows behind the window positioned in the foreground for the cycle time, the window positioned in the foreground at least partially obscuring each remaining window.

3. The method of claim 2 , further comprising:
providing a plurality of tabs in the GUI for selecting the plurality of windows, respectively,
wherein sequentially positioning each window in the foreground of the display comprises sequentially selecting each tab of the plurality of tabs and sequentially positioning each window of the plurality of windows corresponding to the selected tab in front of each remaining window of the plurality of windows for the cycle time.

4. The method of claim 2 , wherein the plurality of channels have predetermined channel numbers, and
wherein the plurality of windows are sequentially positioned in the foreground of the display in an order of the predetermined channel numbers of the select channels respectively producing the corresponding plurality of waveforms.

5. The method of claim 1 , wherein the GUI further includes a time field for inputting the cycle time.

6. The method of claim 1 ,
wherein sequentially emphasizing each waveform in the at least one individual display format comprises sequentially highlighting each waveform of the plurality of waveforms as the viewable waveform in a highlighted condition for the cycle time, while displaying each remaining waveform of the plurality of waveforms in an unhighlighted condition for the cycle time.

7. The method of claim 6 , wherein the highlighted condition comprises a first brightness, and the unhighlighted condition comprises a second brightness that is less than the first brightness, emphasizing the viewable waveform.

8. The method of claim 6 , wherein the highlighted condition comprises a first thickness, and the unhighlighted condition comprises a second thickness that is less than the first thickness, emphasizing the viewable waveform.

9. The method of claim 6 , wherein the highlighted condition comprises a first color, and the unhighlighted condition comprises a second color that is less bright than the first color, emphasizing the viewable waveform.

10. The method of claim 6 , wherein the plurality of channels have predetermined channel numbers, and
wherein the plurality of waveforms are sequentially emphasized in the highlighted condition in an order of the predetermined channel numbers of the select channels producing the plurality of waveforms, respectively.

11. The method of claim 1 , wherein the at least one individual display format comprises at least one of a separate waveforms display format in which all of the plurality of waveforms are displayed in separate, vertically stacked grids, or a tile waveforms display format in which the plurality of waveforms are displayed in separate, divided portions of the display.

12. The method of claim 1 , wherein sequentially emphasizing each waveform of the plurality of waveforms in the overlay waveforms display format comprises sequentially highlighting each waveform as the viewable waveform in a highlighted condition for the cycle time, while displaying each remaining waveform of the plurality of waveforms in an unhighlighted condition for the cycle time.

13. A system for selectively emphasizing displayed waveforms, the system comprising:
a plurality of channels for receiving a plurality of signals and producing a corresponding plurality of waveforms, respectively;
a processor for processing the plurality of waveforms;
a display communicating with the processor for presenting a graphical user interface (GUI), wherein the GUI provides a plurality of graphical elements corresponding to the plurality of channels, a waveform emphasis graphical element for enabling a waveform emphasis feature, a time graphical element, and a plurality of display format graphical elements corresponding to a plurality of available display formats;
an interface communicating with the processor for receiving commands from a user responsive to the GUI; and
a memory communicating with the processor, the memory storing instructions that, when executed by the processor, cause the processor to:
receive through the plurality of graphical elements corresponding to the plurality of channels a selection of a plurality of select channels from the plurality of channels to be viewed on the display;
receive through the time graphical element an indication of a cycle time;
receive through the plurality of display format graphical elements a selection of a select display format from the plurality of available display formats in which a plurality of waveforms from the plurality of select channels are displayable on the display; and
when the waveform emphasis feature is enabled, display on the display the plurality of waveforms of the corresponding plurality of select channels in the select display format by sequentially emphasizing each waveform of the plurality of waveforms as a viewable waveform for the cycle time, while de-emphasizing each remaining waveform of the plurality of waveforms in relation to the viewable waveform for the cycle time,
