If data is being plotted, there should be one graph for each channel. An example graph is shown
below.
Figure 6-1. Example Measurement
Note: Not all return loss measurements will look exactly like the example above. The most important part
of the return loss measurement is to ensure that every point on the return loss line is below the limit
specified by the IEEE 802.3 specification.
