The IAI2 Impedance Analyzer provides all of the functionality offered by the LCR Active Head but with a wider frequency and impedance measurement range plus higher nominal accuracy. This is achieved by a more sophisticated design that includes an addtional internal shunt range, a current amplifier to increase low impedance signal levels and calibration together with the PSM3750 with which it will be used. The IAI2 feature 4 internal shunts plus an internal high frequency amplifier, the combination of the PSM3750 and the IAI2 result in a comprehensive measurement suite.
