About machine
The E4990A is an impedance analyzer from Keysight Agilent. Electrical impedance analyzers enable the measurement and monitoring of the opposition to current in AC, or alternating current, systems. Impedance refers to how the chemical or physical properties interact with voltages and currents, or how well a component passes current. Use an impedance analyzer to test equipment such as capacitors, inductors, and resistors. Applications include Corrosion studies, Battery research and fuel cells, Solar cells, LCDs, Bio-materials, Ceramics / composites, Electronic component development, BioEngineering.
