Product information "Tekbox TBLM1 / LISN-Mate"

LISN-Mate allows the distinction between differential and common mode rejection.

The so-called LISN-Mate TBLM1 is a passive accessory for LISNs, which splits the line-bound signal into its common-mode and differential components. The LISN-Mate is connected to the HF output of the LISN in the positive supply line (LISN 1) and to the HF output of the second LISN in the negative supply line (LISN 2). The line-bound noise signal at the output of the LISN is always the sum of the common mode noise signal and the differential noise signal. The LISN-Mate now splits the two signal components so that they can be measured at the two BNC sockets "Differential Mode" or "Common Mode" separately. It must be ensured that the connecting cables between the two LISNs and the LISN-Mate are identical in length and construction and have very good RF shielding.

The TBLM1 enables efficient troubleshooting of EMI filters in the power supply. Once the dominant noise component is determined, the noise filter components can be more easily identified and optimized. This saves time and money.
