功能簡介

概述

    GRL的UHS-II協議測試儀和主機模擬器(GRL-UHSII-EMU)是與東京電子設備公司(TED)合作開發的唯一一款測試符合SD協會UHS-II協議測試指南1.0版的工具。這種結合的硬體和軟體測試平台為UHS-II卡和主機提供了自我驗證環境,涵蓋了SDA UHS-II協議測試規範中定義的幾乎所有項目,以及用於壓力測試和驗證的設置環境。 GRL-UHSII-EMU可以隨機或連續安排溝通時序或連續識別一段時間內的SD卡性能來驗證UHS-II卡/主機的可靠性。提供易於理解的Pass/Fail測試結果和協議錄製。

    GRL-UHSII-EMU還提供了強大的工具來發現UHS-II卡的真實設計性能,包括錯誤插入和主機發出的資料封包的可編程響應時間。為了識別各種數據長度的實際卡片吞吐量,GRL-UHSII-EMU能夠將數據從1MB傳輸到1GB,並以低功耗和快速模式計算吞吐量。
