Tekbox TBLC08
/ 50 µH two-wire network simulation (V-LISN) up to 240V/8A

The 50µH LISN TBLC08 is a two-wire V-network simulation for measuring unbalanced interference voltages on the mains supply line of devices with a single-phase AC power supply. The interference voltage between the two conductors (phase or neutral conductor) and the earth reference point is measured separately using a changeover switch. The frequency range for EMC precompliance testing according to CISPR 16/EN55011 is 9 kHz to 30 MHz. The TBLC08 network simulation is looped into the supply line of the DUT (Device Under Test). Conducted interference that occurs on the DUT's supply can be measured via the BNC connection in conjunction with a spectrum analyzer or measurement receiver. The network simulation has a switchable attenuator with limiter and 150 kHz high-pass filter. The network simulation is designed for a maximum of 240 V/8 A. The network simulation is constructed with air coils to avoid measurement errors caused by saturation effects.
