Tekbox TBL50100-1B LISN
Details
The Tekbox TBL50100-1B is a single-channel 50µH 100A LISN (Line Impedance Stabilisation Network) used in EMC testing to measure conducted noise on the supply line of DC/AC-powered devices. This LISN is designed according to CISPR 16-1-2 and MIL-STD-461G and is characterised in the frequency range of 10 kHz - 100 MHz. Furthermore, the LISN is placed in the power line of the DUT (Device Under Test). It measures unwanted electrical noise at the supply terminals of the DUT, which can be checked using a spectrum analyser or a measurement receiver. Two TBL50100-1B units can be used in conjunction with the Tekbox TBLM02 LISN mate, allowing common-mode and differential-mode noise to be measured separately. By using multiple TBL50100-1B LISNs, it becomes possible to perform 3-phase measurements.
Please note that when using this LISN without a transient limiter and testing AC-supplied products, it is highly recommended to protect the input of the connected analyser with a high-pass filter such as the Tekbox TBHPF2-150kHz high-pass filter.
For a calibrator that is suitable with the TBL50100-1B LISN, see the TBL05100-1C-CAL calibration kit.
