Figure 3-27. 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.
Once the cursors are no longer necessary, press and hold the CURS button to return to
the Cursor menu and disable the cursor selection submenus. The check mark indicates
the cursor is enabled, and no check marks indicate the cursor is disabled.
To exit the cursor function while leaving the cursors active, just select another mode in
the pane (i.e., Line Select, Variable Gain, etc.).
