TekBox TBLM2 LISN MATE

The TBLM2 is is a Common Mode / Differential Mode – separator companion device for LISN. The LISN Mate is connected to the output of a LISN inserted into the positive supply line and to a second LISN inserted into the negative supply line.

The conducted noise signal at the output of a LISN is the sum of common mode and differential mode noise. The LISN mate separates it into the common mode and differential mode components, with each signal component available at a separate BNC port. The TBLM2 can be used in the frequency range from 9 kHz to 110 MHz.
