The TBL0550-1 5\u00b5H LISN is a device required to setup conducted noise measurements of DC-powered electronic
\nequipment. It is designed to be used for measurements in the frequency range of 150kHz to 110 MHz according
\nto CISPR 16-1-2, CISPR-25, EN55025, MIL-STD-461F, ISO11452-4 and with limitations DO-160\/ED-14G and
\nISO 7637-2.
\nThe LISN is inserted into the supply line of the DUT (Device Under Test). Conducted noise which is present at
\nthe supply terminals of the DUT can be measured at the BNC connector using a spectrum analyzer or a
\nmeasurement receiver. The source (supply) terminal and the DUT terminal are decoupled by a 5\u00b5H inductor.
\nTwo TBL0550-1 in combination with the Tekbox LISN Mate enable separate measurements of common mode
\nand differential mode noise.
\nThe unit comes equipped with a BNC-male to N-male RG232 cable, mating connectors and ground brackets to
\nattach it to a ground plane.<\/p>\n<\/div>\n<\/section>\n
