Setting the bias at this center voltage guarantees linear frequency response profiles across the sensor spectrum. To preserve raw signal integrity in tight multi-probe assemblies, cross-talk suppression requires careful spatial management of the electromagnetic fields emitted by adjacent probe tips. This spatial tuning prevents inductive coupling errors, enabling clean tracking of complex rotor dynamics and high-frequency orbit paths without phase distortion.\u003c\/p\u003e\n\u003ch3\u003eKit Components \u0026amp;
