This doesn't really answer your CISPR question, but, FYI, the USA Mil-Std-461D
does define the LISN construction. It then directs you to add the loss between
the power line and the RF port to the cable loss and the observed signal. Their
limit figure is in terms of dBuV of emission
Patrick,
CISPR 11, other CISPR Publications and FCC conducted emissions limits apply
to the EUT port.
LISN insertion loss should be added. In most cases, especially at higher
frequencies correction
for LISN's insertion loss is negligible to the overall test accuracy and
therefore could be
