The gain was 10dB. With higher gain, the ACPR gets worse with the given input power. I'm sorry that I do not know how to upload the captured spectrum, but it is exactly as I mentioned in the first place: The noise floor is about -50dBm while the in-band signal is at -25dBm over the 8.8MHz of the signal bandwidth. -- Posted via http://www.ruby-forum.com/. _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
