Hello Lauren, Rather than a lengthy explanation, can I point you to the Commission’s R&TTED Reference page...
http://ec.europa.eu/enterprise/sectors/rtte/documents/#h2-2 Follow the link to Equipment Classes where there is an explanation and two fairly recent lists defining Class 1 and Class 2 equipment. Also read section 4 the ‘Guide’ (my constant companion) @ http://ec.europa.eu/enterprise/sectors/rtte/files/guide2009-04-20_en.pdf I did have a little look-see at what goes on at 1700 kHz. Now I’m not sure here but I think you might be encroaching into the AM broadcast band, cordless phone, ship-shore radio, inductive transmission, and amateur radio bands. I’m not sure you can use this band in Europe for data telemetry applications which I what I think you are doing? Particularly for OOKing which is very aggressive in terms of spectrum usage. If others know otherwise... please correct me. Anyway, according to current guidance your kit doesn’t appear to be Class 2. If there are Harmonised Standards for your particular equipment then you’re in the clear and it’s very probably Class 1. If neither then I would suggest you seek advice from a Notified Body who may be able to help. Without knowing much more about the equipment it's impossible to be more specific but I hope this helps. Cheers, T ----- Original Message ----- From: Crane, Lauren Sent: 04/11/13 12:00 AM To: [email protected] Subject: [PSES] How to determine EU RTTE class. I am looking for advice on how to determine the EU RTTE class of a product. The product has a base station and a sensor. The battery powered sensor can be taken out of the base station and used elsewhere to do its sensing thing, and then be brought back to the base station for charging and uploading of the sensed data. The nominal transmit frequency for sense data communication is 1700 KHz +/-100 KHz. The modulation scheme uses On-Off Keying (OOK). The nominal baudrate base station to sensor is 1,000 Hz. The nominal baudrate sensor to base station is 8,000 Hz. Based on this information, can someone help me understand which RTTE class this product is, and why?
