Fig. 5-1 RF output test set-up
(1) Perform AUTO ZERO and AUTO CAL on the power meter.
(2) Connect the test equipment as shown in Fig. 5-1.
(3) On the UUT set:
Carr Freq 30 kHz
RF Level 0 dBm
(4) Record the output level measured by the power meter against each of the carrier frequencies
shown in Table 5-1 checking that the results are within specification.
(5) Set the UUT RF level to +7 dBm and repeat (4) using Table 5-2.
(6) Set the UUT RF level to +25 dBm and repeat (4) using Table 5-3, decreasing the RF level to
+19 dBm when testing at carrier frequencies above 1.2 GHz.

Test procedure
(1) Perform AUTO ZERO and AUTO CAL on the power meter.
(2) Connect the test equipment as shown in Fig. 5-1.
(3) On the UUT set:
Carr Freq 2.5 MHz
RF Level −4 dBm
(4) Record the output level measured by the power meter against each of the steps shown in
Table 5-4 checking that the results are within specification.
(5) Set the UUT carrier frequency to 950 MHz and repeat (4) using Table 5-5.
(6) Set the UUT carrier frequency to 1200 MHz and repeat (4) using Table 5-6.
(7) Set the UUT carrier frequency to 1900 MHz and repeat (4) using Table 5-7.
(8) Set the UUT carrier frequency to 2400 MHz and repeat (4) using Table 5-8.
