Base station analyser with LTE-A CA capability

Click2Contact

Anritsu has introduced functionality for its BTS Master MT8220T base station analyser that enables field users to conduct highly accurate and efficient LTE-Advanced Carrier Aggregation (CA) measurements during network deployment and maintenance. With this capability, the MT8220T can conduct key LTE-Advanced CA measurements for all active component carriers (CCs) and display them simultaneously on the same screen, enabling users to quickly and accurately verify LTE-Advanced CA field installation.

Many LTE-Advanced CA measurements have been automated for simplicity and efficiency. The BTS Master MT8220T automatically detects cyclic prefix configuration to simplify user set-up and prevent measurement errors. An Auto Range feature automatically optimises the analyser configuration for each tuned CC to eliminate user intervention and increase measurement throughput. Automatic MIMO detection enables remote over-the-air (OTA) MIMO verification for all CCs, as well as absolute and delta RS power measurements. Additionally, TAE measurements can be made with the BTS Master MT8220T to troubleshoot and correct excessive timing offsets between CCs. Other measurements that can be conducted include SS power, EVM, and detection of Cell ID.

All measurements can be performed OTA with high accuracy, due to the BTS Master MT8220T’s >25 dB scanner dynamic range. Users can also combine all CCs at a test point for a direct connect measurement. Findings are shown and updated on the large screen in an easy-to-read measurement results table.
