BTS Master MT8220T 是 Anritsu 的第三代高效能手持基站分析儀，此分析儀經過特別開發升級，現在不僅支援 2G、3G 和 WiMAX 網路，還支援 4G 無線網路。 MT8220T 為 LTE eNodeB 測試提供 20 MHz 頻寬解調品質，並裝配了高對比的觸屏顯示器和背光鍵盤，可在強自然光和陰暗的環境下使用。
資深無線技術員和射頻工程師們借助 BTS Master MT8220T 基站分析儀，能夠對基站的安裝和運行情況執行精確、快速的驗證，從而實現最佳無線網路性能並確保對能其進行持續維護和故障排除，以此保持您的無線網路基礎結構以最佳狀態正常運轉。標準3年保固提供世界級的可靠性保障，客戶可安心使用MT8220T BTS Master。
2G、3G 和 4G 網路訊號分析儀能夠測試無線訊號的射頻品質和調變品質，進而可對基站發射器中絕大多數子系統之性能進行驗證。透過包含各自信號分析選項的下行鏈路空中下載 (OTA) 品質測試，您可測試不易接近的遠端射頻頭端 (RRH) 等訊號發射器的效能、解決覆蓋問題，並檢查 LTE 和 TD-LTE 的 MIMO 調變是否正確運行。此外，CPRI/OBSAI RF 量測選項方便使用者連接 CPRI/OBSAI 光纖鏈路以檢查上行干擾問題。
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 call on site.
BTS Master MT8220T 體積小、重量輕且用電池供電，這些特點使得技術人員無論在單元基站的任何地方都能輕鬆地展開工作。該儀器開機預熱時間不到 5 分鐘，既能節省電池電量，又能使您快速地開始您的測量工作。GPS 接收器為其標準功能，結合 Anritsu 的干擾擷取解決方案可方便地進行問題干擾訊號的映射和三角測量。
對於某些關鍵性能指標 (KPI) — 如因單元基站故障或干擾引起的呼叫中斷、呼叫拒絕或呼叫阻塞率 — 您可以藉由集多功能於一體的 BTS Master MT8220T 快速解決遇到的所有問題。對於網路運營商、分包商和安裝員來講，這是唯一一款結合觸控式螢幕、具備有效確認傳輸效能 (line sweeping)、透過 MIMO 測試執行的綜合信號分析、極度靈敏的光譜分析和複雜的干擾追蹤等多種測試功能於一機的輕巧設備。
