The 84661 cable is a calibrated component of the resonant circuit; therefore, any alteration in length or physical damage to the internal coaxial path affects the system frequency response. During operation, gap voltage validation at the -10 VDC target is required to confirm signal fidelity. Cross-talk suppression is maintained by the integrated armour, which provides an additional layer of shielding against electromagnetic interference in dense cabling environments.\u003c\/p\u003e\n\u003ch3\u003eOrdering Information\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003e1 x 84661-75 Armoured Extension Cable\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e2 x Connector installation kits\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eTechnical compliance documentation\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation \u0026amp; Routing Guidelines\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eBending Radius: Maintain a minimum bend radius of 64 mm to prevent deformation of the interlocked stainless steel armour and internal coaxial cable.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eArmour Integrity: Ensure the armour is properly terminated at the junction box using approved fittings to maintain environmental protection and grounding continuity.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eConnection Security: Ensure all connector interfaces are clean and fully seated; use a torque wrench on threaded couplings to established manufacturer specifications.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eEnvironment: The armoured jacket is designed for high-vibration and abrasive environments; ensure the cable is secured with appropriate clamps to prevent fatigue.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eGrounding: The armour is typically used as a secondary shield; ensure it is tied to the instrument earth at the designated termination point to mitigate ground loops.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cul class=\"list-paddingleft-2\"\u003e\n\u003cli\u003e\n\u003cp\u003eQ: Can I use this armoured cable with non-3300 series probes?\u003c\/p\u003e\n\u003cp\u003eA: No. The 84661 series is impedance-matched to 3300 series components.
