5 μH LISN for Tektronix EMC pre-compliance

EMI-LISN5UH (TEKBOX TBOH01 offered by Tektronix)

The EMI-LISN5UH is the TEKBOX TBOH01 5 μH LISN. This device is required to set up conducted noise measurements of DC-powered devices and is designed to be used for EMC pre-compliance testing in the frequency range of 150 kHz to 110 MHz (according to the CISPR-25 standard, ISO 7637-2, ISO11452-2/4/5 and with limitations DO-160/ED-14G). The LISN is inserted into the supply line of the DUT (Device Under Test). Conducted noise that is present at the supply terminals of the DUT can be measured at the BNC connector using a spectrum analyzer or a measurement receiver. The source (supply) terminal and the DUT terminal are decoupled by a 5 μH inductor.

Specifications

5 μH LISN

Frequency range

100 kHz –110 MHz

DC resistance

40 mΩ

Maximum current

10 A

Nominal operating voltage range

10 to 60 V DC (1 GHz when insertion loss measured between DUT terminals and BNC connector; source

Impedance

¹The operating voltage range is limited to 60V DC for safety reasons. Though the component rating of the LISN is ≥ 200V, the positive supply voltage could accidentally be connected to the negative terminal of the LISN and thereby to the LISN housing. Under this circumstance, a DC voltage > 60V could cause a lethal electric shock when touching the housing.
