HP / Agilent 4192A LF Impedance Analyzer, 5 Hz to 13 MHz

The HP/Agilent 4192A LF Impedance Analyzer measures impedance and admittance across the 5 Hz to 13 MHz frequency range, delivering 4½-digit resolution for characterizing components, filters, and materials in development, quality control, and production settings. This analyzer tests both floating and grounded devices with direct readout of 13 impedance parameters—|Z|, |Y|, R, X, L, C, Q, D, and associated phase and loss metrics—plus gain-phase measurements including amplitude, phase, and group delay.
