FAQ: : Does TRZ® Analyzer have a hardware enabling the collection of Phase data in addition to the Impedance data during the frequency sweep? Mr. T.W.
TRZ® Analyzer does not have the hardware for phase measurement. It used to have in early versions, but not anymore.
For general applications, as quality control and maintenance of ultrasonic parts, we concluded that frequencies (Fr&Fa), impedances (Zr&Za), and the mechanical quality factor (Qm) are enough for devices with medium and high Qm (>100). Additionally, we have developed a multiparametric curve fitting algorithm to obtain the BVD equivalent circuit which allowed us to calculate the Qm without knowing the phase information. After these facts and aiming to keep the TRZ Analyzer user-friendly and cost-effective, we have decided to remove the phase circuit.
