  • LISN 5uH - Line Impedance Stabilization Network

Line Impedance Stabilization Network for conducted EMC measurements

V-, Δ- and T-Type LISN 5μH 16A


For development and pre-compliance measurements

For conducted EMI testing an Artificial Main or Line Impedance Stabilization Network is required. The LISN 05/16 is a measurement platform that is compliant with CISPR 25.

This LISN is used to separate the 9kHz - 110MHz band from the DC voltage source and provides a standardized impedance over which is measured.
It can be used as a V-, Δ- and T-network, which makes it ideal for solving EMI problems.

Conducted EMI

Using the built-in DM, CM and single line measurement, the LISN05/16 eases problem analysis to find the origin of a Line interference.

Low/High pass

The selectable low- and high-pass filters eliminate measurement errors due to clipping of the measurement receiver. The filters are combined with a built-in attenuator/limiter that protects the spectrum analyzer from harmfull input transients during power on of the equipment under test.

This measurement instrument has been designed by electronic engineers for electronic engineers who deal with devices that are connected to the Mains like inverters, machines and power supplies.

Use

The circuit used, conforms to the specifications of CISPR-25 with V-, Δ- and T-network measurements.

The simulated impedance is 5μH || 50 Ω in the frequency range 9 kHz to 110 MHz. Filters are provided to reduce the bandwidth.

It is designed to allow for peaks up to 30A without loss of linearity.
