Are you interpreting the other reasons as meaning if one doesn't have a 10
m facility, then it's ok to test

The note in CISPR 22 that allows testing at
alternate distances applies only to class B products.
What is the justification
and the test lab. My
original email was not attempting to justify 3 meter testing, only to point
out that it is allowed.

Stuart,
Cispr 22:1997 clause 10.2.1 answers your question. The earlier version of
Cispr 22 has similar wording.
For Class B equipment you may use a 20 dB/decade extrapolation to correct
measured data, to compare to the limits, at closer distances

The radiated limits are stated for 10 meters but our measurements are at 3
meters. Is it ok to use 3 meter data and what should the new limits be (may
be 10 dB
is allowed for Class A equipment.
Going from 3 to 10 meters: You would subtract 10.5 dB from your
measurements (the formula is given in clause 10.6).

The radiated limits are stated for 10 meters but our measurements are at 3
meters. Is it ok to use 3 meter data and what should the new limits be (may
be 10 dB higher)?
Thanks,
