Page 6 of 22 4.1 DESCRIPTION OF TESTS 4.2 Occupied Bandwidth Emission Limits (a) On any frequency outside a licensee’s frequency block, the power of any emission shall be attenuated below the transmitter power (P) by at least 43 + 10 log(P) dB. (b) When measuring the emission limits, the nominal carrier frequency shall be adjusted as close to the licensee’s frequency block edges, both upper and lower, as the design permits. (c) The measurement of emission power can be expressed in peak or average values, provided they are expressed in the same parameters as the transmitter power. 4.3 Occupied Bandwidth The 99% power bandwidth was measured with …
