TekBox LISN TekBox LISN Series Line Impedance Stabilization Networks
TekBox Modelle TBOH01, TBL0500-1, TBLC08 LISNs
- TBOH01 5 µH LISN according to CISPR 25; conducted noise measurements of DC-powered devices in EMC pre-testing in the frequency range of 150 kHz to 110 MHz. Inserted into the supply line of the device under test (DUT), conducted noise which 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.
- TBL0550-1 5 µH 50 A LISN for conducted noise measurements of DC-powered electronic equipment; designed to be used for measurements in the frequency range of 150 kHz to 110 MHz according to CISPR 16-1-2, CISPR-25, EN55025, MIL-STD-461F, ISO11452-4 and with limitations DO-160/ED-14G and ISO 7637-2. Inserted into the supply line of the DUT, conducted noise which 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.
Two TBL0550-1 in combination with the Tekbox LISN Mate enable separate measurement of common mode and differential mode noise. - TBLC08 50 µH LISN according to CISPR 16; measurement of line-conducted interference within the range of 9 kHz to 30 MHz, according to the CISPR16 standard. Designed for testing single phase, AC-powered equipment with supply voltages up to a maximum 240 V and 8 A. Conducted noise can be measured on the phase and on the neutral conductor. The TBLC08 is equipped with a switchable limiter/attenuator and an artificial hand connection.
- TBL5000 serie 9 kHz to 30 MHz.

Frequently Asked Questions:
Question: What is a LISN and what is it used for?
Answer: LISN is the abbreviation for Line Impedance Stabilization Network (also called AMN/Artificial Mains Network). These are low-pass filters that are usually connected between the DC/AC source and the DUT (device under test). The LISN simulates supply networks (low-voltage network, on-board network of a motor vehicle, aircraft, etc., telecommunications network). LISN are used for both line-based and radio-based EMC (electromagnetic compatibility) tests, which are specified in various standards (e.g. CISPR, CENELEC, MIL-STD, etc.). The tasks of a LISN include the suppression of RF interference that may be present on the supplying network. It also provides a normalized impedance on the line voltage side for the DUT. The LISN also provides a defined connection between the DUT, the supply network and the measuring device: For further measurement and analysis, e.g. with a spectrum analyzer, the LISN ensures the decoupling of RF interference voltage that is superimposed on the supplying mains voltage of the DUT.
