The equipment shall be configured to operate with continuous modulation mode switching at the maximum switching speed permitted by the system, with equal duty cycle for all modulation orders, and with all training bursts or reference signals active as
37、 in normal operation. In spectrum analyser, set the resolution bandwidth according to tables 2 to 9 and also set the video bandwidth to value of three times the resolution bandwidth. True RMS detector shall be used. 5.4.1.1.2 Procedure Step 1 Set the RF channel to the lowest channel centre frequency
38、 from the declared range. Step 2 Make sure the data link connection has been established between BS UUT and Signalling Unit. Step 3 The BS UUT is configured to continuously transmit at Pnom as measured over the 5 MHz or 10 MHz of allocated bandwidth. Step 4 Measure and note the signal spectrum over
39、the range specified in clause 4.2.2.2. Tables 2 to 9 according to the specified measurement bandwidths in the tables. Note that measurement aggregation is needed to compare with specified numbers according to the 1 MHz measurement bandwidth in the tables. Step 5 Repeat Steps 2 to 4 at the middle and
40、 highest RF channel centre frequencies from the declared range. Step 6 Repeat Steps 1 to 5 for all modulation schemes supported by the equipment under test. Step 7 End of test. In the case that BS supports multiple transmit antenna (antenna 1 to N): 1) If single transmit antenna is a valid mode of o
41、peration, Steps 1 to 7 shall be performed on a selected single antenna port with Pnom transmit level. 2) To test the mode with multiple antenna enabled: a) Steps 1 to 7 shall be repeated when all antenna are enabled with a total transmit power of Pnom (e.g. each antenna is transmitting at Pnom - 10
42、log10N level). b) The measurement results of Step 4 are combined (measured power levels are added).
