To access the Eye Pattern display, press the EYE function button on the front panel.
The Eye Pattern display appears in the selected pane, as shown in Figure 3-21 and
described in Table 3-16.
• TVM-40
Select another pane (a pane that does not contain the Eye pattern display), and
press the EYE button again. The Jitter is displayed in the selected pane, as shown
in Figure 3-22 and described in Table 3-17. The time bases are 1H, 2H, 1V, and
2V.
• TVM-10
Press the EYE button again to toggle between the Eye Pattern display and the
Jitter Waveform display, as shown in Figure 3-22 and described in Table 3-17.
The time bases are 1H, 2H, 1V, and 2V.
Pressing and releasing the EYE button continuously without changing the pane will
toggle between the Eye pattern and Jitter Waveform display.
In the Jitter display, press and hold the EYE button to select the JITTER WAVEFORM
MODE menu. Selectable modes are Waveform Sweep (jitter vs. time), as shown in
Figure 3-22; or Frequency Sweep (jitter vs. frequency), as shown in Figure 3-23 and
described in Table 3-18. These displays show the relative amplitude of the jitter versus
time or versus the frequency at which it occurs. The Jitter Frequency display is useful
to determine the frequency of major jitter components.
Simply pressing the EYE button in the Jitter display changes the display to eye pattern.
Any other pane that contained the Eye pattern display will change to a blank screen
containing the instruction “SELECT NEW FUNCTION.”
