    HIGHLIGHTS

    信號分析

    • 支援 CMMB 標準
    • 使用 PXA BBIQ 或 MXA BBIQ 硬體進行發射器射頻量測與類比基頻量測
    • 具有單鍵量測功能,並可依據標準判定合格/不合格,提供自動偵測功能
    • 可在 PXA、MXA 和 EXA 信號分析儀上執行

    量測功能

    • 功率量測: 通道功率、肩部衰減、ACP、CCDF、OBW、SEM
    • 調變準確度量測: 星狀圖、MER/EVM(MER RMS、副載波的 MER、依據資料計算的 MER、連續前導和分散前導、MER 與時槽)、頻率誤差、振幅誤差、相位誤差、正交錯誤、振幅不平衡
    • 通道頻率響應、通道脈衝響應和頻譜平坦度
    • 自動偵測或手動設定 CMMB 信號;提供進階設定功能,例如等化切換、每個插槽的解調變符碼、頻帶外濾波、以及時脈速度

    效能(取決於硬體配置)

    • 功率準確度: 高達 ±0.19 dB(第 95 百分位數)
    • 肩部衰減動態範圍: 高達 98.4 dB(103.7 為典型值)
    • MER 位準: 高達 48 dB(對於 1 至 39 時槽和 16QAM,關閉資料均衡)
    • 分析頻寬: PXA/MXA 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

    CMMB 是中國行動多媒體廣播標準,由中國國家廣播電影電視總局 (SARFT) 制定與指定。這項標準可將 QVGA 畫面傳送到 GPS、PDA 與手機等小螢幕裝置,採用衛星與地面互動式多重服務基礎架構 (STiMi)。Keysight N6158A CMMB 量測應用軟體,提供單鍵標準式功率與調變分析功能,可協助您設計、評估和製造 CMMB 調變器、發射器、放大器、調諧器和電波空隙補強器/中繼器。
