                        Impedance Measurement and Analysis Solutions
Impedance measurement instruments are employed for development and characterization, and for sensors, electronic components, electrochemical cells, and materials tests. They can extract complex impedance vectors at a single test condition, or while sweeping source parameters like frequency, amplitude, and dc bias.
