    HIGHLIGHTS

    信號分析

    • LTE FDD 符合標準 3GPP 第 9 版標準
    • 使用單一選項進行上行鏈路(OFDMA)和下行鏈路(SC-FDMA)射頻發射器量測;可用 PXA 或 MXA BBIQ 硬體進行類比基頻量測
    • 可分析所有LTE通道和信號: RS, UE-RS, MBSFN-RS, P-RS, P-SS,S-SS, PBCH, PCFICH, PHICH, PDCCH, PDSCH, PMCH, PUCCH, PUSCH, PRACH,
    • SRS 和 DM-RS
    • 可在 PXA、MXA 和 EXA 信號分析儀上執行

    量測功能

    • 基地台 (eNB): 錯誤向量幅度 (EVM)、頻率誤差、DL RS功率、發射器分支之間的時間校準、RSTP、RSRP、OSTP、發射開/關功率、頻譜放射遮罩 (SEM)、鄰近通道洩漏比 (ACLR) 等
    • 使用者設備 (UE): EVM、頻率誤差、I/Q 偏移、頻譜平坦度、頻段內輻射、發射開/關功率、SEM、ALCR 等等
    • 傳輸層通道解碼: 存取解對映、解交錯、解擾碼、解速率匹配與解碼資料。
    • 使用多種顏色編碼的結果顯示:EVM 對子載波、EVM 對符號、EVM 對插槽、EVM 對資源區塊 (RB)、偵測到的配置 (子載波對符號)、錯誤摘要表、訊框摘要表等。

    效能(取決於硬體配置)

    • 殘餘 EVM,5 MHz 下行鏈路信號: 最高 0.34%(標稱值 0.28%)
    • ACLR,5 MHz E-UTRA 鄰近通道: 最高 -83.5 dB (標稱值)
    • 絕對功率準確度: 最高 ±0.19 dB
    • 分析頻寬: PXA 機型高達 160 MHz;EXA 機型高達 40 MHz

    其他特色

    • 可升級的授權碼
    • 提供固定與可轉移授權
    • SCPI 遠端操作介面

    Keysight LTE FDD 量測應用軟體是 Keysight X 系列超過 25 套量測應用軟體的其中一套,可全面提昇量測儀器、量測方式以及量測軟體之信號分析效率。 此應用軟體可將 Keysight X 系列信號分析儀,轉變成符合產業標準的發射器測試儀。它提供射頻相符性量測功能,以協助您設計、評估及製造 LTE FDD 基地台和用戶端裝置。 此量測應用軟體嚴格遵循 3GPP 標準,能讓您克服設計與製造挑戰並保持領先優勢。

    射頻發射器測試

    • 可自動偵測下行鏈路通道與信號,大幅簡化量測設定 可重新呼叫 E-TM 預設值,以便根據 3GPP TS 36.141 相符性標準檔,執行並簡化 eNB 相符性測試
    • 可在所有 LTE 通道頻寬上,以及所有通道與信號上執行量測,並可依資源區塊、子載波、插槽或符號等條件來檢視量測結果。 具色彩編碼及標記連結的圖形顯示,讓您能更快找到問題並迅速解決。
    • 利用傳輸層解碼功能進行實體層以外的測試。 在接收器鏈路的各點上存取資料,以便解決傳輸層問題並驗證通道編碼的正確性。這些資料包括: 解對映、解交錯、解擾碼、解速率匹配與解碼資料。
    • 較於傳統 EVM 量測,「相符性 EVM」量測功能最高可將製造測試速度提高兩倍在生產製造方面,「相符性 EVM」的量測速度比傳統 EVM 的量測速度快 2 倍。此外,具有寬廣分析頻寬選項(大於 40 MHz 頻寬)的 PXA 或 MXA 可提供硬體加速的 EVM 量測,其速度最多提高 3 倍。
    • 在 PXA 或 MXA 信號分析儀中新增即時頻譜分析儀(RTSA)功能,以便發現操作頻段中其他發射器,或是發射器事件所產生的干擾
