The center frequency, fC, is measured at the minimum insertion loss point, ILMIN,
with the resonator in the 50 Ω test system (VSWR ≤ 1.2:1). The shunt
inductance, LTEST, is tuned for parallel resonance with CO at fC. Typically,
fOSCILLATOR or fTRANSMITTER is approximately equal to the resonator fC.

Typically, equipment utilizing this device requires emissions testing and
government approval, which is the responsibility of the equipment manufacturer.

frequency, fO. The nominal frequency at any case temperature, TC, may be
calculated from: f = fO [1 - FTC (TO -TC)2]. Typically oscillator TO is
approximately equal to the specified resonator TO.
9. This equivalent RLC model approximates resonator performance near the
resonant frequency and is provided for reference only. The capacitance CO is
the static (nonmotional) capacitance between the two terminals measured at low
frequency (10 MHz) with a capacitance meter. The measurement includes
parasitic capacitance with "NC” pads unconnected. Case parasitic capacitance
is approximately 0.05 pF. Transducer parallel capacitance can by calculated as:
CP ≈ CO - 0.05 pF.
