Our calibration lab is ISO-17025 accredited to calibrate for Line Impedance Stabilization Network (LISN): Insertion Loss Impedance for EMC/EMI Testing and Compliance.
A LISN is a device used in conducted and radiated radio-frequency emission and susceptibility tests, as specified in various electromagnetic compatibility (EMC)/EMI test standards (e.g., by CISPR, International Electrotechnical Commission, CENELEC, U.S. Federal Communications Commission, MIL-STD).
A LISN is a low-pass filter typically placed between an AC or DC power source and the EUT (equipment under test) to create a known impedance and to provide a radio frequency (RF) noise measurement port. It also isolates the unwanted RF signals from the power source. In addition, LISNs can be used to predict conducted emission for diagnostic and pre-compliance testing.
Our LISN Calibration Services parameters are listed below.
