The HP/Agilent 41941A Impedance Probe Kit extends the measurement capabilities of the HP/Agilent 4194A Impedance/Gain-Phase Analyzer to 100 MHz. This grounded probe accessory delivers accurate impedance characterization of in-circuit components, PCB patterns, and circuit input/output impedance across a broad measurement range. The kit supports DC biased measurements for comprehensive component evaluation.
