The TEKBOX TBLM01 is a companion device for LISNs, which splits the conducted noise signal into its common mode and differential mode components. 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 splits it into the common mode and differential mode components, with each signal component available at a separate BNC port. The TEKBOX TBLM1 is supplied with 2-off BNC-male to BNC-male RG223 cables, 35cm long. For further information, please refer to the 'SPECIFICATION' and 'DOCUMENTS, SOFTWARE & VIDEOS' tabs, above.
