- Separates common-mode and differential-mode noise for more detailed conducted emission analysis.
- Works with two LISNs connected to positive and negative supply lines.
- Provides separate BNC ports for each noise component.
- Wide usable frequency range from 9 kHz to 110 MHz.
- Designed for use with spectrum analyzers or EMI receivers in EMC test setups.
TBLM2
LISN Mate
The Tekbox TBLM2 LISN Mate is a common-mode and differential-mode noise separator designed to be used with Line Impedance Stabilisation Networks (LISNs). When connected to the outputs of two LISNs (one on the positive and one on the negative supply line), it separates the total conducted noise into common-mode and differential-mode components, making it easier to analyze and diagnose noise sources in EMC testing setups
