Transducer Factor: Transducer Factor for LISN?

Question

I cannot find any transducer factor for my LISN.

Do I need one?

Answer

The LISN is clearly and exactly defined in the CISPR 16 standard.

LISN that comply with this standard have only very small variations of the measurement result. This variation is so small that it can be ignored.

Therefore, you do not need a transducer factor for a LISN that complies with CISPR 16.

However, the ENV216 is an exception to the rule. Due to a built-in pulse limiter, a 10 dB correction factor

should be inserted as a constant from 9 kHz to 30 MHz.
