Line Impedence Stabilization Network | EM-7825-1 | 450 kHz – 100 MHz

The Electro-Metrics EM-7825-1 Line Impedance Stabilization Network (LISN) is a two channel low pass filter network designed to isolate an electrically operated device from an external power source. The EM- 7825-1 is used when high frequency conducted measurements are made in accordance with certain FCC, CISPR and VDE standards.

Applications

When measuring conducted radio interference voltages from line to ground, it is essential to stabilize the line impedance so that repeatable tests can be made at more than one facility. The Electro-Metrics series LISN’s are designed to meet FCC, VDE and CISPR standards for conducted emissions measurements. Each LISN is designed to present a relatively constant impedance to high frequency signals that may be present on the power lines between the device under test and the power source.
