(4)Measure the level of the second and third harmonics on the spectrum analyzer at each of the carrier frequencies shown in Table 5-15 checking that the results are within specification.

(5)Set the UUT RF level to +7 dBm and repeat (4) using Table 5-16.

(6)Set the UUT RF level to +13 dBm and repeat (4) using Table 5-17.

(7)Set the UUT RF level to +19 dBm and repeat (4) up to 1.2 GHz using Table 5-18.
