Intona Professional IDS+VNA Impedance Controlled USB cable – Vector Network Analysis (VNA) tested/measured and individually serialized USB cableSignal Integrity The key to highest Signal Integrity? Constant Impedance vs. cable length Highest possible impedance continuity is a key for excellent signal integrity Any change in impedance causes a reflection of energy The reflected energy causes echo effects which disturb original signal The resulting effects are similar to those of Jitter the natural enemy in any audiophile HiFi System Intonas Innovation: the first commercial USB 2. 0 Hi Speed
