The E4990A Impedance Analyzer has a frequency range of 20 Hz to 120 MHz. The E4990A provides an industry best 0.045% (typical) basic accuracy over a wide impedance range, with a 40 V built-in DC bias source. The equivalent circuit analysis function supports seven different multi-parameter models and helps you to simulate your own equivalent parameter values of components.
The TBOH01 5H LISN is a device required to setup conducted noise measurements of DC-powered devices. It is designed to be used for EMC pre-testing in the frequency range of 150kHz to 110 MHz.
The system complies with DL/T621-1997 standards of Grounding of AC Electrical Equipment , used to test grounding system, connected resistance and soil resistivity of large power plants and substations. It makes up for the defect of traditional measuring approaches, offering complete test items and reliable test for large grounding system
