Measuring: Phase Error/Frequency Error
The RMS and Peak Phase Errors and Frequency Error are shown, along with the
marker readouts if the marker is activated. If the actual data exceeds the limits in
the graph, one (or two for two fails) white triangle marker indicates the failed
position at the top of the graph frame. Any data indicating a failure is highlighted.
