Eye Pattern Cursor Selections

Cursors are available for precise measurement of waveform voltage and

waveform time. Press the CURS button on the front panel to enable the

cursors for the selected pane. The Time Cursor indication is in the

lower-right portion of the screen, and the amplitude cursor indication is in the lower-

left of the screen as shown in Figure 3-19.

Figure 3-19. Establishing Cursor Select for Eye Pattern

To enable the time and/or amplitude cursors, press and hold the CURS button. Use the

NAVIGATION buttons or knobs to select Amplitude or Time. Once selected, press the

ENT button to enable it. Once one or both cursors are selected, press the EXIT button

to exit the CURS pane menu.

When the cursor is selected, the indication will appear at the bottom of the display

along with the cursor line. The horizontal cursor line is the AMPLITUDE line. The

vertical line is the TIME line.

If both TIME and AMP are displayed, pressing the CURS button will select which

cursor to control. In all cases, the TIME or AMP numeric readout at the bottom of the

display indicates the difference between the REF and DELTA lines. The active line

(REF, DELTA, or both) is shown with small arrows at both ends of the line.

Once a cursor is selected for control:

1. Press the CURVED ARROW knob to select the REF or DELTA line to control.

The REF line is the solid line, and the DELTA line is the dotted line.

2. Rotate the knob to move the REF or DELTA line to the desired location.

3. Press the knob for the next line. Rotate the knob to move the other line to the

desired location.

4. Press the knob a third time to control both the REF and DELTA lines.

5. Repeat as necessary.
