10dB attenuator of the LISN

Question:

The LISN ENV216 has an attenuator of 10 dB constantly in the RF path.

Can you tell me that this attenuation is automatically incorporated or has to be entered manually as a fix value?

Answer:

The 10dB attenuator is an additional attenuation of the signal, please take this additional attenuation into account once using the LISN. Please add this to the measured signal with a fixed factor or a transducer.
A built-in pulse limiter which can be switched off protects the receiver input.
