A.1 Assessment of BER at the output of a transmitter

37.1133GPPMulti-Standard Radio (MSR) Base Station (BS) Electromagnetic Compatibility (EMC)NR, E-UTRA, UTRA and GSM/EDGERelease 17TS

The BER at the output of the transmitter may be assessed using either of the techniques described below.

A.1.1 Assessment of BER using static layer 1 functions

The transmitter under test shall be operated according to the test case of TS 51.021 [10], subclause 6.1.2.

The bit sequence from the output of the transmitter shall be monitored by the test system according to the test case of TS 51.021 [10], subclause 7.1.2, and the BER of the class 2 bits for TCH/FS assessed. The BER shall not exceed the values specified in subclause 6.1 of the present document.

If the EUT does not support TCH/FS, the manufacturer shall declare the logical channel for which the performance shall be assessed, and the corresponding performance criteria.

A.1.2 Assessment of BER using RXQUAL

The output of the transmitter shall be connected to an equipment which meets the requirements of TS 51.010-1 [33] for the assessment of RXQUAL. The level of the signal supplied to the equipment should be within the range for which the assessment of RXQUAL is not impaired. The RXQUAL shall be monitored during the test. The RXQUAL shall not exceed the values specified in subclause 6.1 of the present document.

NOTE: This equipment can be a GSM mobile station with suitable provision for the monitoring of RXQUAL.
