Hello,

 

Typically the only ‘radio’ (Article 3.2) testing you would most likely do is 
the transmitter spurious emissions (or any other ‘radiated’ style tests).   
Transmitter/Receiver antenna port measurements (like bandwidth, duty cycle, 
etc.) are often not re-tested at the host level.

 

But for Article 3.1b (EMC), pretty much ‘nothing’ carries over from a module to 
a host; which is why radiated immunity of the radio link is always re-tested at 
the host level.

 

 

Michael.

Assume:

*       Non-radio equipment fully comply.
*       Radio module fully comply.

 

The combination radio module into the Non-radio equipment, the only test to 
conduct on the final product is spurious emission according to relevant radio 
standard.

This I have been told by NB.

They did not mention immunity tests at all.

 

 

Cheers!

Emne: Re: [PSES] RED ZigBee 6 GHz Immunity Testing: Technical Risk?

 

Dear group, 

did anyone ever answer Mike’s question for his ZigBee device?  I’ve got the 
same question, but I’m using a Bluetooth radio.  

 

Is a completed radio product required by the RED to be tested for radiated 
immunity to 6 GHz?  In other words, must the finished product match RI 
considerations of the radio?  Is this “in addition to” the product family 
standard, which may only prescribe RI to 3GHz? 

 

Thank you,

Chet Summers

Esteemed colleagues:

I've got what I'm told is a fully RED compliant ZigBee module that goes into 
equipment that I'm told now must be immunity tested to 6 GHz the RED (the chip 
reportedly already passes). Connections to my equipment are data and power. We 
have no experience immunity testing the equipment from 3 to 6 Ghz. I'm trying 
to assess my risk as I wait for lab time to open up.

 

QUESTION: has anyone had immunity problems in other than radio modules in the 
3-6 GHz range? How common? Were they found in certain constructions or 
components?

 

thanks again to all,

Mike Sherman
