Dear All I have a question about the limits of Singapore'standard. I have performed the test under TS10(Singapore) for RFID system. The maximum limit of this standard is 94 dBu/Vm. The carrier data of our measurement of this product was 60 dBuV/m. The spurious data was 40 dBuV/m. And this standard says that "emissions shall be at least 32dB below the carrier frequency"
If this case.... [1] 60 (dBu/Vm) - 32 (dBu/Vm) = 28 (dBu/Vm) [2] 94 (dBu/Vm) - 32 (dBu/Vm) = 62 (dBu/Vm) Which spurious limit ([1] or [2]) should we comply with ? If we MUST comply with [1], this limit (28 dBu/Vm) is very strict and then the product is not complied with this standard. I have already asked to Singapore government but I could not get the reply. Please advise me.
