D.1.1 IAB output power, output power dynamics, transmitter ON/OFF power, frequency error, EVM, unwanted emissions for IAB type 1-H
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 for IAB type 1-H
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.
