32、on The maximum output power is the maximum value of the mean power over any specified time interval, delivered to a load with resistance equal to the nominal load impedance of the transmitter. The manufacturer or person responsible for placing the equipment on the market shall declare the maximum va
33、lue of the mean output power for the base station. The maximum value of the mean output power shall be recorded in the documentation. The accuracy of the maximum output power is the maximum allowable error between the measured value and the declared value of the mean output power, when the transmit
34、time slot are at their maximum power setting. Within each slot, the Pilot, MAC and Traffic or Traffic control channels are time-division multiplexed. All time-division multiplexed channels shall be transmitted at equal power. This test measures the time response of the mean output power for non-idle
35、 slots and the mean power at the RF output port. 4.2.3.2 Limits The maximum output power shall be within +2 dB and -4 dB of the manufacturers declared output power for the equipment.

The test for radiated spurious emissions shall be performed on
38、 a representative configuration of the equipment under test. 4.2.4.2 Limits The frequency boundary, reference bandwidths and the limits are based on CEPT/ERC Recommendation 74-01E 15 covering spurious emissions. The requirements, are shown in table 6. The base station shall not exceed the limits giv

NOTE 2: If the test system for a test is known to have a measurement uncertainty greater than that specified in
41、table 7 or 8, this equipment can still be used, provided that an adjustment is made follows: square4 Any additional uncertainty in the test system over and above that specified in the table is used to tighten the test requirements - making the test harder to pass (for some tests, e.g. receiver tests
42、, this may require modification of stimulus signals). This procedure will ensure that a test system not compliant with table 7 or 8 does not increase the probability of passing an EUT that would otherwise have failed a test. 5.3 Essential radio test suites 5.3.1 Transmitter conducted unwanted emissi

For multiple carrier systems the following test procedure shall be performed with the system set to operate on the maximum number of contiguous carriers using the highest and lowest group of carrier frequencies as declared by the manufacturer. 5.3.1.1 Test procedure Refer to TIA-864 7, figure
