LISN for CISPR 25 & 16-1-2, DO-160, MIL-STD 461

The LI-350 LISN for DO-160, MIL-STD 461F, CISPR 25, and CISPR 16-1-2.

The LI-350 Line Impedance Stabilization Network (LISN) provides the necessary measurement platform for performing power line conducted emissions compliance testing as required by most worldwide standards for commercial products. The LI-350 is compliant with both RTCA DO-160 and MIL-STD 461F.

The concept and advantages of the LISN is to:

a) connect in series with, and impose a defined impedance on, the lines under test, thereby providing a distinct advantage over current or voltage probe measurements, where the impedance of the lines is largely uncontrolled;

b) provide a coaxial RF measurement port for connection to the measurement equipment, to which the disturbance voltages present at the EUT port are coupled for measurement; and,

c) isolate the AE (ancillary equipment) port from the EUT and RF ports, which:

    1) minimizes the influence of the AE-connected equipment/cabling on the impedance (and voltage division factor) of the network; and,

    2) reduces the amplitude of any ambient signals and spurious disturbance voltages generated by the AE-connected equipment, thereby minimizing their potential impact on the measurement results.

Two pairs of LI-350 can accommodate 3-phase power systems (Wye or Delta configurations).
