D.1.1 AAS BS output power, transmitter ON/OFF power, modulation quality, frequency error and operating band unwanted emissions

TAB connectors may be connected to the measurement equipment singularly and tested one at a time (figure D.1.1-1), or may be tested simultaneously in groups (figure D.1.1-2) where the group size may range from two to all the TAB connectors which are subject to particular transmitter test in this test setup.

In all cases the measurement is per TAB connector but the measurement may be done in parallel.

D.1.3 Transmitter spurious emissions

TAB connectors may be connected to the measurement equipment singularly and tested one at a time (figure D.1.3-1), or may be tested simultaneously in groups (figure D.1.3-2) where the group size may range from two to all the TAB connectors which are subject to transmitter spurious emissions test.

In all cases the measurement is per TAB connector but the measurement may be done in parallel.
