Here is another application for the AEA graphical Complex Impedance Analyzer that is described in their manual.  You can not only find the resonant frequency of your traps, you can also see the relative Q factor.  The CIA-HF will instantly display the minimum SWR point as well as the 2:1 upper and lower frequency points while you examine the actual swept curve.  It will sweep up to a 10 MHz spectrum in only 1 second.

Do not recall section, but they list a metho of checking traps.
