The Thurlby Thandar TTI-1600 50 µH is a Single Phase LISN. The Thurlby Thandar TTI-1600 50 µH LISN is predominantly used for Conducted Emissions testing, being utilised by placing it between the power supply and EUT to accurately measure the interference that the EUT is emitting at its supply input.

Where would this be used? The Thurlby Thandar TTI-1600 50 µH LISN is used to supply the connected equipment with a known, reliable impedance and isolating the equipment from the power source, preventing external noise from interfering with measurements.
