The Keysight 42941A is an impedance probe kit designed for use with the 4294A Precision Impedance Analyzer (and compatible models like the E4990A). It enables highly accurate in-circuit impedance measurements over a wide frequency range from 40 Hz to 110 MHz, providing a convenient probe-style interface for component and circuit testing.
