It is important, however, to use the circuit
recommended by BS 6305 for return loss
measurements.
The LM-NP-1000 Series are EN 41003
approved.

* Due to the unique design and the most advanced manufacturing techniques the 2 coils are fully identical, meaning there is no real
primary nor secondary winding. Depending on the application, the transformers can be used either way.
