The Com-Power LI-350 Line Impedance Stabilization Network (LISN) can handle upto 50 Amps AC (35Amps DC) current and provides the necessary measurement platform for performing power line conducted emissions compliance testing as required by DO-160 & 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 (ancilliary 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, as well as spurious disturbance voltages generated by the AE-connected equipment, thereby minimizing their potential impact on the measurement results.

Two pairs of LI-350 can be used to accommodate 3-phase power systems (Wye or Delta configurations).
All LI-350 LISNs are individually calibrated in compliance with the relevant requirements of RTCA DO-160 and MIL-STD 461F. Impedance and Insertion Loss data is supplied with each unit, along with the calibration certificate.  (also LI350)
