Antenna Analyzer AIM4170 page 32
Measurement of Crystal Parameters
Quartz crystals can be modeled as shown below:
The series resonant frequency is the lower of the two frequencies. It’s determined by L
and Cs. The higher parallel resonant frequency is determined by L and Cp+Cs.
A broad scan can be done to locate the resonant frequencies. They will be displayed at
the top of the screen. Typically, these two frequencies only differ by a few kilohertz.
(The screen pictures in this section were taken using an AIM430. The same features are
included in the AIM4170.)
