Frequency plots
WireScope 350 can display frequency plots for swept frequency measurements.
This view of the data provides a very complete picture of the performance of the
cabling run under test compared to the required test limit.
To launch the frequency plot screen for any swept frequency measurement,
select the measurement from the Test Data screen. If a frequency plot is
available for the selected measurement, the Plots button will appear at the
bottom of the screen. Press the Plots button.
The Plots screen shows frequency plots for all of the measured pairs or pair
combinations. For some measurements, plots from both the WireScope 350 and
DualRemote 350 are superimposed on the same set of axes.
The frequency cursor is set to the point with the worst margin by default when
the Plots screen appears. You can move the frequency cursor to any point by
either touching in the plot area or by using the
to the worst case point at any time by pressing the Worst Absolute button, or
back to the point with the worst margin by pressing the Worst Margin button.
