LISN Line Impedance Stabilization Network Pseudo Power Supply Circuit Network

Designed to test three-phase and single-phase AC power supplies with a maximum supply voltage of 450V/260V and 32A.

**Product Overview** The TBL5032-3 is a line impedance stabilization network that measures conducted interference in the range of 9 kHz to 30 MHz, in accordance with the CISPR 16-1-2 standard. This device is designed to test three-phase and single-phase AC power supplies with a maximum supply voltage of 450V/260V and 32A. Conducted noise can be measured on each phase and the neutral line. The TBL5032-3 features individual RF outputs for each phase and neutral, allowing it to be combined with the TBLM1 to separate emissions into common mode components and differential mode components. While the TBL5032-3 does not have an integrated high-pass filter for the RF output, it comes with an external 9 kHz coaxial high-pass filter. The single-phase DUT socket is available in country-specific variations.

LISN Line Impedance Stabilization Network Pseudo Power Circuit Network

2-pass 50 Ω LISN characterized by 30Hz to 500MHz // 1 µH

**Product Overview** The TBL0110-2 LISN is a 2-path 50 Ω // 1 µH LISN characterized by a frequency range of 30 Hz to 500 MHz. It is based on the standard ECSS-E-ST-20-07C Rev 1. This standard provides a general schematic for LISNs and allows for some flexibility in component values. The implementation of the TBL0110-2 is intended for use in EMC measurements of small satellites and spacecraft. The LISN does not have an output for conductive radiation measurements; instead, it functions solely as a network to stabilize line impedance. An RF current monitoring probe is used to measure conductive radiation in accordance with the standard. The 1 µH inductor mimics the typical inductance of power wire harnesses in small spacecraft and satellites. The LISN is inserted into the power line and power return line of the EUT.

5μH, 50A power supply impedance stabilization circuit network

Compliant with CISPR 16-1-2, CISPR 25, EN 55025, and MIL-STD-461F standards.

**Product Overview** The TBL0550-1 5µH LISN is a device necessary for setting up conducted noise measurements of electronic equipment powered by DC sources. It is designed to comply with CISPR 16-1-2, CISPR-25, EN55025, MIL-STD-461F, and ISO11452-4, and is intended for measurements in the frequency range of 150kHz to 110MHz, with limited use of DO-160 / ED-14G and ISO7637-2. The LISN is inserted into the supply line of the DUT (Device Under Test). Conducted noise present at the power terminals of the DUT can be measured using a spectrum analyzer or measurement receiver via a BNC connector. The source (power) terminal and the DUT terminal are decoupled by a 5µH inductor. By combining two TBL0550-1 units with the Tekbox LISN Mate, common mode noise and differential mode noise can be measured separately. The unit is equipped with a BNC male to N male RG232 cable, a coupling connector, and a ground bracket for connection to a ground plane.

LISN Line Impedance Stabilization Network Pseudo Power Supply Circuit Network

Universal 5µH LISN

**Product Overview** The TBL05100-1 is a universal 5µH LISN that meets the requirements of several standards. The TBL05100 is factory-jumpered to 50Ω // 5µH + 1Ω, complying with the impedance and phase isolation specifications of CISPR 16-1-2 and CISPR 25. By setting the internal jumper, it can be converted to a 50Ω // 5µH variant that supports standards such as CISPR 25, MIL-STD-461G, ISO11452-4, and ISO 7637-2. Adding an external 10F capacitor will adjust the impedance to meet DO-160 specifications. The LISN is inserted into the power line of the EUT (Equipment Under Test). The conducted noise from the EUT's power terminals can be monitored via a BNC connector using a spectrum analyzer or measurement receiver. The 5µH inductor isolates the source (supply) terminal from the EUT terminals. Using two TBL05100-1 units in combination with the Tekbox LISN Mate allows for the separate measurement of common mode noise and differential mode noise.
