From 100 to 250% of the authorized bandwidth they are attenuated by at least 35 dB and beyond 250% 43 + log(Po) dB. The plot show the transmitter modulated with 15000 Hz(the highest modulation frequency), adjusted for 50% modulation plus 16 dB. The spectrum analyzer was set with the un-modulated carrier at the top of the screen. The test procedure diagram and occupied bandwidth plots follow.
