7. Press the Graph (F2) key to access the peak phase error graph.
A typical peak phase error graph is shown above.
Two types of pass/fail results are provided:
• An overall measurement pass/fail indicator is positioned in the bottom left 
corner of the display:
— The text “Pass” is shown in a green-colored font if the all of the phase and 
frequency error measurements (peak phase error, RMS phase error, and 
frequency error) have passed. 
— The text “Fail” is shown in a red-colored font if any of the phase and 
frequency error measurements have failed.
• Individual pass/fail indicators are provided for the peak phase error, RMS 
phase error, and frequency error. On the display, text labels corresponding to 
these measurements change color to indicate a pass or fail (green indicates a 
pass; red indicates a fail).
