Hi David, I would have thought they would keep it at the 80% 1kHz AM modulation, so potentially 30V/m CW calibration, then apply the modulation on the test run, to give 54V/m peaks?
But as you said, pulse might make more sense as it replicates mobile phone/wifi devices better maybe. This would open up a lot of re-testing on products that comply with the current standards. Rob.

As Rob mentioned, the requirement could be up to 30 V/m. If you’re intended to use the normal AM modulation of IEC 61000-4-3, that’s up to 54 V/m during your calibration. Pulse modulation makes more sense, but it isn’t in the draft.

Up until that point, it will be a combination of EN 55032 and either EN 55024, 55020 or 55103-2? Thanks, Regards Rob.

It appears that the CISPR FDIS is forecast for October 2016, and CENELEC will for sure need time to process it into an EN. With best wishes DESIGN IT IN!

With EN 55035 still in draft form, are we likely to see that become compulsory the same time EN 55032 does? (ie 5th March 2017?) In addition, do we know what the Radiated Immunity test changes are likely to be on the final version of the draft? I’ve seen that there is a new requirement for spot frequencies at 1.8GHz, 2.6GHz, 3.5GHz and 5GHz @ 3V/m. However, I have also seen talk of a ‘Protection Distance’ which could increase this 3V/m up to 30V/m.
