NOTE 2: If the test system for a test is known to have a measurement uncertainty greater than that specified in tables 10 and 11, this equipment can
39、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, this may require modification
40、of stimulus signals). This procedure will ensure that a test system not compliant with tables 10 or 11 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 emissions 5.3.1.1 Initial condition

45、.1.3. 6) Set the input amplitude of the signal such that the output signal is at the declared maximum power rated by the manufacturer. 7) Measure the power level at the carrier frequency. 8) Measure the transmitter conducted unwanted emission levels using appropriate resolution bandwidth at the offs
46、et frequencies specified in the relevant table in clause 4.2.2 for the band class under assessment. 9) Increase the power level of the input signal by 10 dB and repeat steps 7 and 8. 10) If the repeater supports two or more carriers, input two CDMA channels in any combination of supported carriers a
47、s defined in clause 5.3.1. 11) Set the input amplitude of the signals such that the output signals are at the declared maximum power rated by the manufacturer taking into consideration the ratings for multiple carrier operation and perform steps 12 and 13. 12) Measure the transmitter conducted unwan
