LISN (100 Amps) for DO-160, MIL-STD 461 & CISPR 25/16

Model: LI-3100

10 kHz - 400 MHz

LI-3100

DO-160, MIL-STD 461, CISPR 25 and CISPR 16

Line Impedance Stabilization Network (LISN) Model: LI-3100 can handle upto 100 Amps AC (70 Amps DC) current and provides the necessary measurement platform for performing power line conducted emissions compliance testing as required by DO-160 & MIL-STD 461F and CISPR 25 and CISPR 16 from 10 kHz to 400 MHz.

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-3100 can be used to accommodate 3-phase power systems (Wye or Delta configurations).
