IMHO, there is no cost effective EMC facility, but you don't have to spend all your bucks all in the one day. A sound and well managed EMC business growth program could see you through.
Start off with pre compliance and eventually branch off into formal compliance (by drafting up a Quality System to ISO 25 or whatever, a few test procedures and a few Quality and third party Technical Audits) Buy a 2nd hand shielded room today with a view to lining it with ferrite tiles and/or RAM material such that you meet the Radiated Immunity 16 point check for immunity and alternative sites 3 m NSA for emissions. Initial RE prescans could be done here. Buy a 26 GHz cheap ($25000/-!!) analyser (without preselector) driven by software for now and then go for a $100000/- preselectable receiver suitable for formal CISPR measurements and also MIL 462 related work. Start off with a chicken wire mesh car park OATS and improve later; not much hope in Singapore because of the ambients, but you could always go to Malaysia or setup a Sea Plane or a salt water based site (you will get very good NSA, probably won't need NSA). Lastly, performing ESD, EFT and Surge tests in a shielded room/ anechoic chamber will make you very popular among your colleagues because of the additional filtering within the shielded room.

Thanks those who share with me your experience. I may not address my problem very clearly thus I would like to come back to you one more time. We are a R & D orgnization in Singapore mainly dealing with semiconductor industry. Since there are some requirements from our industry partners in the area of EMC design, we are considering setting up some EMC measurement capabilities. At the intial stage, we will only consider equipment for radiated emission/susceptibility testing. Our objective is to evaluate the EMC performance of the product from our customers, being of PCB level or system level. Based on those results, we can help our customers to improve their product EMC design so that their product can pass the final compliance testing. The EUT could be small, such as integrated circuits on PCB, but it can also be large such as a PC. Due to our budget constraint, I think GTEM maybe a good choice. Do you guys agree ? If not, any other suggestions ? Thanks in advance. Best Regards Qu Pingyu --------- This message is coming from the emc-pstc discussion list.
