tracking function is enabled, the instrument detects and moves the main marker to the
minimum |Z| value each time it has completed one sweep cycle.
You can determine the self-resonance frequency and resonant impedance by reading the
sweep parameter (frequency) and measurement parameter values indicated by the main
marker that appears in the upper-left area of the graph for Trace A. In the example shown
in Figure 2-9, the DUT exhibits its self-resonance frequency and resonant impedance at
approximately 5.13 MHz and 155 mW, respectively.
