The BTS Master MT8220T is Anritsu’s third generation high-performance handheld base station analyzer that has been specifically developed to advance the support for 4G wireless networks as well as installed 2G, 3G, WiMAX networks, CPRI/OBSAI RF, and BBU Emulation. The MT8220T provides 20 MHz bandwidth modulation quality for LTE eNodeB testing and is equipped with a high-contrast, touch screen display and backlit key panel making it simple to use in both bright sunlight and dim conditions.
The BTS Master MT8220T Base Station Analyzer is the essential multi-function instrument for senior wireless technicians and RF engineers to accurately and quickly verify the installation and commissioning of base stations for optimal wireless network performance and for the on-going maintenance and troubleshooting to keep wireless network infrastructure fine-tuned. A standard three-year warranty demonstrates world-class reliability and brings peace-of-mind to owning and using the MT8220T BTS Master.
The signal analyzers for 2G, 3G and 4G networks can test the RF quality and modulation quality of a wireless signal to verify the performance of virtually every subsystem in a base station's transmitter. With the downlink over-the-air (OTA) quality tests included with each signal analysis option you can test the performance of transmitters that are difficult to access like remote radio heads (RRH), troubleshoot coverage problems and for LTE and TD-LTE, check that the MIMO configuration is correctly working. Also, a CPRI/OBSAI RF measurements option allows the user to check for uplink interference problems by conveniently connecting into the CPRI/OBSAI fiber link.
The new, patented PIM over CPRI option is a non-intrusive method of measuring passive intermodulation (PIM) using live traffic over the Common Public Radio Interface (CPRI) link. It is set to change the dynamics of PIM detection by enabling users to test at ground level, any time of the day – with no site turn down required. By tapping into the CPRI data on the downlink and uplink between the remote radio head and baseband unit, the BTS Master MT8220T can calculate the PIM desensitization of the LTE uplink. In addition, the PIM over CPRI measurement option will also determine if the PIM found is internal or external to the antenna system, which is useful in deciding whether a tower crew needs to be called on site.
The BTS Master MT8220T is small, lightweight and battery operated making it easy for the technician to use it anywhere at a cell site. With less than 5 minute warm-up time you get more useful battery life and you can start making measurements sooner. A GPS receiver is a standard feature allowing convenient mapping and triangulation of problematic interference signals in conjunction with Anritsu's interference hunting solutions.
When it comes to meeting key performance indicators (KPI) such as dropped calls, call denial or call blocking rates owing to a malfunction at the cell site or interference, the BTS Master MT8220T is the all-in-one instrument that you can count on for quick problem resolution. For network operators, sub-contractors and installers it is the only fully integrated, touch screen hand held tool which combines line sweeping, comprehensive signal analysis with MIMO testing, ultra-sensitive spectrum analysis and sophisticated interference tracking in a compact, easy-to-use instrument.
