Utilizing the EYE Display (TVM-VTM-EYE-H,

TVM9100PKG-EH, TVM9100PKG-ES, TVM9140PKG-EH,

TVM9140PKG-ES)

NOTE: Available for Inputs A and B only.

The Eye Pattern display is created by sampling the serial digital signal with the

recovered serial clock. The Eye Pattern display is used to measure signal amplitude,

jitter, rise time, and other irregularities. Measurement of the transition widths is done

by manually setting the cursors on the transition limits of the display and reading the

offset in picoseconds (ps). The amount of jitter can also be estimated from the bar

display above the Eye Pattern display. Amplitude is similarly measured using cursors.

To access the Eye Pattern display, press the EYE function button on the front panel.

The Eye Pattern Display Diagram is displayed in Figure 3-15 and described in Table

3-11.
