ETSI cannot specify intermodulation products as they depends from your implementation. The system is interested in overall performance degradation, so BER.
Can you explain in detail?
If you want to measure internal system parameters (gain, noise, linearity) you should have a system partitioning study or specification that gives you the expected values so you can measure it.
It sound strange that you are designing something but you have measurement issues. Could you please explain more in detail it to better understand?
Thank Mazz firstly.Because we want to evaluate the demo board,It is my first time design digital RF,i think it is different with FM system,and i need more informations about digital RF measurement firstly.especially IM product,linearity.
.in band and out band block.
I hope it can help.
Always thanks for your kindness
