If you do your own calibration you need to follow the requirements in ISO 17025
for calibration labs. This requires that you calculate your measurement
uncertainty, where a test alb is only estimating the uncertainty.

The reason for the 1.8 factor is that you are calibrating with a CW signal.
When you switch the modulation on in real testing the peak level for the
amplifier will be in the range of 1.8 of the CW level. It’s just a
pre-caution not to overdrive the amplifier.

used for so many years by a huge number of
people and many of them seem to have the phone glued to the ear.
If there is any impact we should have seen a significant increase in certain
areas like cancer. This didn’t happen therefore I believe the influence is
close to none.

Neven,
I think you are right. The advantage to use antennas calibrated as a pair is
that the Measurement uncertainty is a little bit smaller.

Yes the DoC is issued by the party placing the product on the market.
There are some labs trying to sell certificates which looks like a DoC, but
this is not the the right way defined in the EMC directive of the EU.

I guess the EN 55014-1,2 would be more applicable regarding EMC in Europe.
However the ETSI depending on the answers from Massimo can cover already a
good part and should be seen in combination to the EN.

is only specified up to 300 MHz. At higher frequencies the
cables act different.
This method was used e. g. simple household devices and tools.
I don't know if I got the real point because I didn't followed the whole
