TBLDC32-2
DC-Line Impedance Stabilization Network
The Tekbox TBLDC32-2 is a specialised DC Line Impedance Stabilisation Network (LISN) used for conducted emissions testing on DC supply lines. It provides a defined and stable impedance between the DC power source and the equipment under test (EUT) to enable accurate noise measurements with a spectrum analyzer or EMI receiver in accordance with CISPR 16-1-2 and CISPR 11 standards. The front-panel rotary switch allows selection between common-mode and differential-mode measurements, making it effective for advanced EMC testing.
