The HP 4274A and HP 4275A Multi-frequency LCR Meters are microprocessor-based impedance measuring instrumentation. Both instruments offer LCR components, complex components, electronic circuits "test under actual working conditions" and semiconductor materials. A measurement under conditions similar to the intended use contributes to the improvements in quality and reliability of electronic components, devices and circuits.
