Grace, Any good Calibrated Noise Emitter at the correct frequency range is a good source for checking your OATS or chamber. There are "Round Robin" programs offered by a couple groups that can anonymously show results of your lab compared to other labs participating. When testing actual products what must be remembered is that every EUT will look different from one site to the next due to setup and test distance, among other variables. Also, EUT's are generally "distributed" RF sources and data taken at 3m will often show surprising difference if measured at 10m even if set up identically. Bill

Should I purchase a signal source? If yes, do you have any reference? I do have a COM-POWER comb generator and don't know if it is good enough for the purpose. Should I use an EUT for site comparison? Thank you. Best regards, Grace Lin - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
