Abstract

A method and apparatus for identifying a point on a rendered signal. The rendered signal comprises display-points that correspond to sampled points. A portion of the sampled-points is displayed. A sampled-point is selected from the portion displayed. The signal is rendered on the display to include the display point corresponding to the sampled-point.

Claims

1. A method for identifying a display-point on a rendered signal, the rendered signal comprising display-points, the display-points corresponding to sampled-points of a signal, the method comprising:

displaying a portion of the sampled-points;

selecting a sampled-point from the portion of the sampled-points; and

rendering the signal, wherein the rendered signal includes the display-point corresponding to the selected sampled-point.

2. The method of claim 1, wherein the step of displaying the portion of the sampled-points comprises the step of displaying the portion of the sampled-points in a table.

3. The method of claim 1, prior to the step of displaying the portion of the sampled-points, the method further comprises the steps of:

rendering the signal;

selecting one display-point as an initial display-point; and

wherein the portion of the sampled-points in the step of displaying the portion of the sampled-points includes a sampled-point corresponding to the initial display-point.

4. The method of claim 1, wherein the step of rendering the signal to include the display-point comprises the step of displaying indicia at the display-point.

5. The method of claim 1, wherein the step of rendering the signal to include the display-point comprises the step of centering the rendered signal at the display-point.

6. The method of claim 1, after the step of rendering the signal to include the display-point, the method further comprises the step of displaying a different portion of sampled-points, wherein the different portion of the sampled-points includes the selected sampled-point.

7. The method of claim 1, wherein the step of rendering the signal comprises the step of rendering the signal in a magnified view.

8. The method of claim 1, wherein the step of displaying the portion of the sampled-points includes displaying Meta Data of the sampled-points.

9. The method of claim 1, wherein the portion of sampled-points is the same as the sampled-points.

10. A measurement system comprising:

a computer readable media for storing sampled-points of a signal;

a display adapted to display a portion of the sampled-points;

an input device communicating with the display to select a sampled-point from the portion of the sampled-points; and

a processor unit coupled to the computer readable media, the input device and the display, the processor unit for rendering the signal on the display, wherein the rendered signal includes a display-point corresponding to the selected sampled-point, and the rendered signal comprising display-points corresponding to a part of the sampled-points.

11. The system of claim 10, further comprising indicia, the indicia being displayed at the display-point.

12. The system of claim 10, further comprising:

an initial display-point, wherein the display is adapted for rendering the signal comprising the initial display-point, and wherein the portion of the sampled-points comprises a sampled-point corresponding to the initial display-point; and

indicia, wherein the initial display-point is identified by the indicia on the display.

13. The system of claim 12, wherein the initial display-point is identified by a preselected point on the display.

14. The system of claim 10, wherein the measurement system is an oscilloscope, a spectral analyzer, or a computer based measurement device.

15. The system of claim 10, wherein the input device is a mechanical device on the measurement system or a soft key on the measurement system.

16. The system of claim 10, wherein the portion of the sampled-points is displayed in a table and comprises a display movement mechanism for varying a viewable portion of the sampled-points.

17. A computer readable media containing code thereon, the code providing instructions to a system for executing the steps of:

displaying a portion of the sampled-points;

receiving a command input to select a sampled-point from the portion of the sampled-points; and

rendering a signal at a display-point corresponding to the selected sampled-point.

18. The computer readable media containing code thereon as recited in claim 17, prior to the step of displaying a portion of the sampled-points, the code providing instructions to the system for executing the additional step of receiving the sampled-points of the signal.

19. The computer readable media containing code thereon as recited in claim 17, wherein the step of rendering the signal at the display-point comprises the step of displaying indicia at the display-point.

20. The computer readable media containing code thereon as recited in claim 17, the code providing instructions to the system for executing the additional step of rendering the signal in a magnified view.
