Tekbox TBL5032-1 Line Impedance Stabilisation Network (LISN)
Single-path LISN for conducted emission measurements according to CISPR 16-1-2 and MIL-STD-461G, 10 kHz–100 MHz, up to 32 A and 500 V DC.
The Tekbox TBL5032-1 is a single-path Line Impedance Stabilisation Network (LISN) designed for conducted emission measurements on AC- and DC-powered electronic equipment. The unit is designed according to CISPR 16-1-2 and MIL-STD-461G and characterized over a frequency range of 10 kHz to 100 MHz.
A selectable jumper allows the impedance to be configured as 50 Ω // 50 µH according to CISPR 16-1-2 or 50 Ω // (50 µH + 5 Ω) for MIL-STD applications. The unit supports continuous currents up to 32 A and operating voltages up to 500 V DC or 270 V AC at 50/60 Hz.
By combining two TBL5032-1 units with a Tekbox LISN Mate, common-mode and differential-mode noise can be analyzed separately. For three-phase equipment, three or four LISN units are required, depending on the supply configuration.
The exposed stainless steel bottom panel allows direct connection to a ground plane. An RG223 coaxial cable with N-male connectors is included.
