Hello, I’m an engineer from Spain and I’m interested in a GSM receiver because I would like to study the internal signals for a research project. In particular, I’m interested in the analysis of the IF signal, but, as Alexander told me, the LMS6002D uses zero-IF architecture, so there is no real "IF" signal, there is only baseband signal. I guess I could also use this signal for my purposes, but only if all 124 GSM channels can be found at that point. I’m not sure if this is possible, since there is a low-pass filter before. Does anybody know if I can extract that information, that is, the analogic 124 channels after the RF mixer? If it is not possible with this board, does anybody know if I can do it with another GSM transceiver board? Thank you very much in advance. Best regards, Albert
