7.2.4.2 Procedure
The minimum requirement is applied to all TAB connectors, the procedure is repeated until all TAB connectors necessary to demonstrate conformance have been tested; see clause 7.1.
1) Connect TAB connector to measurement equipment as shown in clause D.2.1. All TAB connectors not under test shall be terminated.
2) Set all TAB connectors declared in the same RAT and operating band to transmit a signal according to clause 4.12.2 at manufacturers declared rated output power PRated,c,TABC.
3) Start the signal generator for the wanted signal to transmit:
– 12,2kbps DPCH with reference measurement channel defined in annex A in TS 25.141 [18] (PN-9 data sequence or longer) for UTRA FDD,
– UL reference measurement channel (12.2 kbps) defined in clause A.2.1 in TS 25.142 [20] for UTRA TDD 1,28Mcps operation
– The test signal mean power as specified in clause 7.2.5.3 for E-UTRA to the TAB connector.
– The test signal mean power as specified in clause 7.2.5.4 for NR to the TAB connector.
4) For UTRA FDD disable the TPC function.
5) Set the signal generator for the wanted signal power as specified in clause 7.2.5.
6) Measure:
– BER according to annex C in TS 25.141 [18] for FDD UTRA.
– BER according to annex F in TS 25.142 [20] for TDD UTRA.
– Throughput according to annex E in TS 36.141 [17] for E-UTRA and NR.
In addition, for multi-band TAB connector(s), the following steps shall apply:
7) For multi-band TAB connectors and single band tests, repeat the steps above per involved band where single band test configurations and test models shall apply with no carrier activated in the other band.
