Description

EMCO’S LISN Model 4825/2 is a two-line, low pass, filter network used for conducted emissions measurements. The product is placed between the power mains and the equipment under test (EUT) to stabilize line impedance, provide a 50 ohm RF connection, and eliminate unwanted RF signals from the line supply.

LISNs play an important role in achieving test accuracy. Without a LISN, conducted interference on the power mains can disrupt measurement reliability. Also, line impedance variances from one test site to another can degrade repeatability. With a LISN integrated into the test system, conducted RF interference is filtered and stable line impedance is assured.

The Model 4825/2 is designed and tested in accordance with IEC Publication 1010, Safety Requirements for Electronic Measuring Apparatus. It has also received CSA safety certification from the Canadian Standards Association, a further indication of EMCO's commitment to safety.

This product covers the frequency spectra of 9 kHz to 30 MHz and is designed to be used with a signal analyzer for making FCC 15, VDE 0871 & 0875, EN 55022 and CISPR 22 conformance measurements.
