TBL5032-1 50uH Line Impedance Stabilisation Network LISN – CISPR 16

The TBL5032-1 is a single path 50µH (+5 Ω) // 50 Ω LISN for conducted emission measurements of DC or ACpowered electronic equipment. It is designed according to CISPR 16-1-2 and MIL-STD-461G standards and characterized in the frequency range of 10 kHz to 100 MHz.

Setting a high current jumper shorts the 5 Ohm resistor and configures it as 50Ω // 50µH LISN according to CISPR 16-1-2. Removing the jumper configures the LISN to (50µH + 5 Ω) // 50 Ω for MIL-STD application.

The LISN is characterized from 10 kHz to 100 MHz.

Combining two LISN with the Tekbox LISN Mate enables separate measurement of common mode and differential mode noise. EUTs with 3 phase supply require three or four pieces of TBL5032-1, depending on whether the product is supplied in delta or star configuration.

An exposed bottom panel enables convenient ground plane connection. The unit comes equipped with a N-male to N-male RG223 cable.
