Keysight (Agilent) N5450B InfiniiMax Extreme Temperature Extension Cable

The Keysight N5450B InfiniiMax Extreme Temperature Extension Cable extends the measurement reach of InfiniiMax I/II/III/III+/RC series differential probes into environmental chambers, enabling signal acquisition across demanding thermal test scenarios. This 92 cm matched cable pair maintains signal integrity during temperature cycling in automotive electronics validation, cellular device conformance testing, and hard disk drive endurance characterization. The probe amplifier remains external to the chamber while probe heads interface directly within extreme temperature environments.
