LISN Line Impedance Stabilization Network Pseudo Power Supply Circuit Network

Designed to test three-phase and single-phase AC power supply devices 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 circuit diagram 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 measuring conducted emissions. Instead, it functions solely as a network to stabilize line impedance. An RF current monitoring probe is used to measure conducted emissions 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.

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 configuring 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). 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 terminal. When two TBL05100-1 units are used in combination with the Tekbox LISN Mate, common mode noise and differential mode noise can be measured separately.
