Eye-Diagram Analyzer Reference

Using Markers

Use this menu to activate the four available line markers: X1, X2, Y1, and Y2.

Markers allow you to measure or compare portions of the displayed waveform.

For example, you can use markers to measure the peak-to-peak difference in a

laser’s turn-on time as measured on the eye-diagram’s crossing point.

Use the front-panel knob or numeric keypad to position each displayed

marker on the screen. Notice that the value at the marker is displayed on the

top portion of the screen. To turn the markers off, simply press MARKERS

OFF.
