DC LISN Bundle — Complete Setup for Conducted EMC Pre-Compliance Measurements

The TekBox DC-LISN-Combo1C DC LISN Bundle is a complete setup for conducted EMC pre-compliance measurements on DC-powered devices. It combines a line impedance stabilization network (LISN) with a common-mode/differential-mode separation unit for full noise analysis.

Package Contents

2× Tekbox TBL0510-1 DC LISN
1× Tekbox TBLM02 LISN Mate
1× BNC termination plug
2× N-plug to BNC-plug 75 cm RG58 cables
1× BNC-plug to BNC-plug 35 cm RG223 cable

Component 1: TBL0510-1

The TBL0510-1 is a cost-effective 5 µH LISN designed for conducted emission measurements over a frequency range from 100 kHz to 400 MHz. It complies with CISPR 25 (EN 55025), various automotive manufacturer standards, MIL-STD-461F, DO-160, AECTP-500, and ISO 7637-2.
LISNs are connected in series with the power supply lines of the EUT (Equipment Under Test). Conducted noise present at the DUT (Device Under Test) power terminals can then be measured via the BNC connectors using a spectrum analyzer or EMI receiver. A 5 µH inductor isolates the supply side from the DUT side, ensuring stable and repeatable measurement conditions.
Using two TBL0510-1 units together with the Tekbox LISN Mate allows separate measurement of common-mode and differential-mode noise.

Component 2: TBLM02 — LISN MATE

The TekBox TBLM02 LISN MATE is a companion device for LISNs that separates common-mode and differential-mode conducted noise. It connects to the outputs of two LISNs: one inserted into the positive supply line and one into the negative supply line. Since the output signal of a LISN contains both common-mode and differential-mode noise components, the TBLM02 separates these and provides them individually at dedicated BNC output ports.
