The TBOH01 5µH LISN is a device required to set up performed noise measurements of DC powered devices.
It is designed to be used for EMC pre-testing in the frequency range 150kHz to 110 MHz.
- The LISN is inserted into the supply line of the DUT (Device Under Test).
- Line noise 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 5µH inductor.
- LISN MATE for Common/Differential Mode conducted noise measurements.
- TBLM1 is an accompanying device for LISNs that splits the leading noise signal into its common mode and differential mode components.
- LISN MATE is connected to the output of one LISN inserted in the positive supply line and to a second LISN inserted in the negative supply line.
- The leading noise signal at the output of an LSIN is the sum of common mode and differential mode noise.
- The LISN MATE splits the signal into common and differential parts, each available on a separate BNC port.
- The frequency range of the device is 30kHz to 110MHz, with a maximum input at any BNC port of 27dBm and below 30mA.
- With 2 parts LISN plus a LISN MATE, the joint noise can be separated into its common mode and differential mode components.
- Using this information, EMC filters can be designed much faster and more efficiently.
- The LISN Mate is supplied with two 14" BNC-BNC cables.
