In Figure 4-4, the more familiar log magnitude response is showing the input match
improvement at 375 MHz. Trace 1 (shown in yellow with marker MK1) is the trace of the
tuned circuit.

In the electronic (PDF) file of this user guide, the traces are shown in color, and are
therefore easier to distinguish.
In the printed grayscale images, M1 drops smoothly from approximately 0 dB to
approximately –6 dB and utilizes marker MK2. Trace 1 (TR1) has nearly the same
end points, but dips to –18.05 dB, as shown at marker MK1.
