Handheld instruments analyses LTE Advanced Carrier Aggregation
The BTS Master MT8220T which combines 30 instrument functions in one device, automatically detects cyclic prefix configuration to simplify user setup and prevent measurement errors. An Auto Range feature automatically optimizes the analyzer configuration for each tuned CC to make user intervention redundant 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, due the BTS Master MT8220T’s superior >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.
Enhancements have also been made to the BTS Master MT8220T spectrum analysis and cable and antenna analysis capabilities. The built-in spectrum analyzer has added support for easyTest so less-experienced technicians can conduct accurate testing, achieve repeatable results, and have less rework. When the analyzer is in cable and antenna analysis Distance-to-Fault (DTF) mode, an added time marker display has been created for more accurate measurements and compensation for cable delays to enhance the precision of geo-location services in VoLTE systems.
Besides enabling measurement on 4G network base stations, the device also supports 3G and 3G networks.
