At present, the hottest topic of 5G NR communications is the application of EN-DC under 5G NR NSA. Although the CE mandatory standard has not been formally introduced, it is known from relevant information that the RF standard will be ETSI EN 301 908-25, and the complete EN-DC RF standard refers to 3GPP TS 38.521-1 & 3GPP TS 38.521-3.

RF test items are mainly used to test tramsmitter and receiver characteristics, such as Max Output power, Minimum Output power, Spectrum Emission Mask(SEM) and Adjacent channel power ratio (ACLR). These are typical emission test items.

Recently, BTL has been in a position to perform Sub-6G FR1 (SA/NSA) test. 

The following two figures are an example of our testing ACLR with Keysight and Anritsu instruments respectively. 

For continuous information about 5G NR test, please pay attention to BTL official account " BTL检测".
