Richard:
My quick answer to your question is no. You ought to end up with the rated
0.2 dB insertion loss, or pretty close to it.
I presume that the insertion loss was measured in a 50 ohm system (could
also be 75 ohm or whatever) as the difference in power at a matched load

I am adding a RF device into my transmission path, and the device has a VSWR
of 1.2 and an insertion loss of 0.2. Will I end up with a total loss of 0.6
dB due to a loss of 0.4 dB due to the VSWR plus the 0.2 dB insertion loss?

I believe that the diagram is for indicative purposes and attempts to show
all test configurations.
Thus when I perform this testing I use one continuous earth plane to which
the EUT is earthed mounted on 10cm supports (if the EUT is not floor
standing). Have a look at figure 9.
Thanks
Ian
Refer to figure 9 in EN 61000-4-4 where the reference plane is
clearly the floor. My interpretation is that the reference plane
shown under the clamp in figure 7 is the floor, unless the test room
floor is not earthed (eg concrete), when an earthed plane covering
the area of the clamp must
Cecil,
What products are you marketing in those countries?
If someone told you that there is no EMC requirement in those countries, that
could be dangerous simply because they do have for certain types of products.
Are you seriously looking for answers from this group? Without specific

Therefore to comply, you must have a report to TS001 and a report to AS/NZS
