Measuring: Phase Error/Frequency Error
The RMS and Peak Phase Error and Frequency Error are shown along with the
marker readout 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.
If there is no limit value set in either HI Limit or LO Limit, “-----” is shown for a
value.
