The EMI-LISN5UH is the TEKBOX TBOH01 5 μH LISN. This device is required to set up conducted noise measurements of DC-powered devices and is designed to be used for EMC pre-compliance testing in the frequency range of 150 kHz to 110 MHz (according to the CISPR-25 standard, ISO 7637-2, ISO11452-2/4/5 and with limitations DO-160/ED-14G). The LISN is inserted into the supply line of the DUT (Device Under Test). Conducted noise that is present at the supply terminals of the DUT can be measured at the BNC connector using a spectrum analyzer or a measurement receiver. The source (supply) terminal and the DUT terminal are decoupled by a 5 μH inductor.
