Frequency Response Analyzer

  • The Impedance Analysis Interface is an optional measurement interface intended to be used in conjunction with the PSM1700 and PSM1735 to form a high accuracy Impedance Analyzer.
  • The IAI 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 PSM1700/PSM1735 with which it will be used.
  • The LCR Active Head and IAI/IAI2 convert the PSM1700/1735/3750(IAI2 only) units into high performance LCR meters with true 4 wire Kelvin connections that are taken directly to the component.
  • without need for external shunts. Buffering, amplification, and selectable shunts provide LCR measurements over a wide frequency and impedance range.
