Hi,
We are doing conducted emssions testing ( to 30MHz) on the following offline (AC mains connected) products.
Lighting
IT equipment
Lab equipment
Class A, B etc
plus many other types of equipment
But despite googling widely , cannot find the site which tells which is the latest standard for the particular category, and gives a comparison of the limit lines.

Hi again...
Also, does anybody have a good youtube video on how to use the PMM Emission suite software with the
PMM 7010 EMI receiver (includes internal LISN)? (for conducted Emissions scans to 30MHz)
At the moment, a number of co's have sent us loads of mains kit to scan, and we get the same conducted EMC
scan whather or not there is anything plugged in to the receiver.(!)
I found two youtube vids but they do not give the detail needed.
Working through the manual is also seeming like they expect some huge prior knowledge
We also have an ETS LINDGREN N5000 maisn filter upstream of the PM7010, and are trying to find out what "cable factor" we need
to use otherwise our readings will be wrong, because not calibrated.
LISN
Also, the PMM7010 manual has the PMM7010 using an external LISN (s attached)....and that LISN is closely
bonded to the vertical ground plane...but we are using the internal LISN inside the PMM7010
so wonder how to bond that internal LISN to the ground plane?
In fact, i doubt the PMM7010 has an internal LISN....the manual seems unclear of this?

Also, pg 1-8 of the PMM7010 users manual says not to overload the PMM7010 or esle it may get
damaged.
Do you know what this means, it refers to pg 1-3, but its not clear how you can avoid "not damaging"
it.

Also, as you know, the first measurement to take when setting up the
Conducted emissions setup, is the "noise floor" measurement, where
nothing is connected to the EMI receiver, and it should report
no emissions, (or very little).
Do you know how we can do this "noise floor" measurement?
At the moment we are above the EN55015 limit lines even when we have nothing
connected.
