Re: [PSES] LED Chamber Lighting - drivers outside the chamber

If the multi-string controllers are switched-mode, then we have the RFI problem again. Or, can the switching frequency be set to 500 Hz, so the 10th harmonic becomes 5 kHz which is below 9 kHz ? twisting the wires will also help for the frequency range 9 kHz to 30 MHz. Rene Charton

Re: [PSES] FCC - Intentional Radiators, Restricted Bands and 960 MHz - conducted measurements would not be helpful

I think conducted measurements would not be helpful anyway, because in this case the use of a conservative antenna gain value is required. (see page 8 of 558074 D01 DTS Meas Guidance v01) Kind regards Rene
