cmu200 gsm burst
thanks to martinthorn and vfone
Our RF solution use low IF , the control loop for PA is open loop . the power into the PA is inside the spec of PA .
We use CMU200 to test modulation spectrum , the result is OK at low PCL , but for Agilent8960 , fail occurs. when the bursts to be test set 100 , it's OK at 8960 .
martinthorn , could you tell me the spec (dBm) for modulation spectrum at Low PCL , the spec said it's -60 dBc when more than 400K.
