TekBox TBLM02 LISN LISN MATE Common Mode and Differential Mode Separator

TekBox TBLM02 LISN LISN MATE Common Mode and Differential Mode Separator

The TekBox TBLM02 LISN MATE is is a common mode/differential mode separator companion device for LISNs. The TBLM02 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 TBLM02 LISN MATE can be used in the frequency range from 9 kHz to 110 MHz.

• Nominal frequency range 150 kHz...100 MHz, usable frequency range 9 kHz...110 MHz.
• Port impedance:
  |ZLISN1|, |ZLISN2|, |ZCM|: 150 kHz...1 MHz: 30...55 Ω, 1 MHz...30 MHz: 50...60 Ω, 30 MHz...100 MHz: 50...70 Ω.
  |ZDM|: 150 kHz...1 MHz: 30...50 Ω, 1 MHz...30 MHz: 40...50 Ω, 30 MHz...100 MHz: 40...70 Ω.
  |ZLISN1|: Independent of the termination at the LISN2 port.
  |ZLISN2|: Independent of the termination at the LISN1 port.
  |ZCM LISN1-LISN2|: 25 Ω nominal.
  |ZDM LISN1-LISN2|: 100 Ω nominal.
• Maximum RF level at any BNC port: 27 dBm.
• Maximum DC current at any BNC port: 30 mA.
