LTE-A Base Station Transmitter Tests

3GPP TS36.141 defines conformance tests for EUTRA base stations (eNodeB). Release 13 (LTEAdvanced Pro) added several tests, especially for Narrowband Internet of Things (NB-IoT). This application note describes how all required transmitter (Tx) tests (TS36.141 Chapter 6) can be performed quickly and easily by using signal and spectrum analyzers from Rohde & Schwarz. A few… Read more »

1MA195: LTE-A Base Station Receiver Tests

3GPP TS36.141 defines conformance tests for EUTRA base stations (eNodeB). Release 12 (LTEAdvanced) added several tests, such as those for contiguous and non-contiguous multicarrier and/or carrier aggregation (CA) scenarios. This application note describes how all required receiver (Rx) tests (TS36.141 Chapter 7) can be performed quickly and easily by using vector signal generators from Rohde… Read more »
