詳細信息
IQ2011測試系統(tǒng)采用多個硬件模塊提供多任務(wù)測試功能，讓GPS與FM兩種無線標(biāo)準(zhǔn)群組可與Wi-Fi、WiMAX、藍牙與近場通訊(NFC)標(biāo)準(zhǔn)群組進行平行測試。多個向量信號產(chǎn)生器(VSG)能針對FM、GPS、Wi-Fi、藍牙、WiMAX、以及NFC等傳輸測試作業(yè)提供傳輸訊號。多個向量信號分析器(VSA)則提供比對功能，讓系統(tǒng)進行接收測試。
　　IQ2011測試系統(tǒng)包含專門支持各種通訊標(biāo)準(zhǔn)(Wi-Fi802.11a/b/g/n、Bluetooth1.0/2.0/2.1、GPS、FMTX/RX、WiMAX802.16d/e與NFC)的軟件函數(shù)庫。用戶可利用內(nèi)置的圖形化用戶接口(GUI)或C++軟件應(yīng)用程序接口(API)，來選取各種信號產(chǎn)生與分析例程。IQ2011捕獲到的數(shù)據(jù)會通過USB2.0傳送到主控端計算機加以處理。C++API支持所有GUI功能，這使其可以輕松建立自動化測試程序，進行制造或設(shè)計特性分析的測試。
　　系統(tǒng)包含4個射頻組件連接端口。其中兩個分別支持GPS與FM，另外兩個是公共端口(RF1與RF2)，用來連接被測試的Wi-Fi、WiMAX與藍牙子系統(tǒng)。
　　IQ2011測試系統(tǒng)滿足所有支持連接無線功能在射頻校正、驗證以及測試的需求。該系統(tǒng)僅須一次插入，并使用單一連結(jié)，就能測試多個無線功能。射頻通訊端口的多樣性提供線路彈性。使用者可同時測試單一通訊調(diào)變，或測試多重?zé)o線裝置調(diào)變功能。IQ2011也可與手機測試系統(tǒng)配合使用，在一臺測試機上支持完整的智能型手機測試程序。
　　利用多任務(wù)測試模式，IQ2011在依序測試Wi-Fi與藍牙通訊功能的同時，還能平行進行GPS與FM的序列式測試模式。這種功能可降低高達75%的整體測試時間。
　　針對Wi-Fi測試采用序列式測試模式，用戶可縮短傳送多重數(shù)據(jù)率EVM/功率量測，以及接收封包錯誤率所耗費的時間。在*種情況中，IQ2011系統(tǒng)配合待測器件(DUT)，以不同數(shù)據(jù)傳輸率送出信號。再加上組件驅(qū)動器以及測試程序的支持能力，IQ2011系統(tǒng)能一次捕獲多個突發(fā)數(shù)據(jù)率，并減少其自身與待測器件之間的通訊時間，進而縮短6倍的傳送測試與校正時間。

The LitePoint IQ2011 is a single system capable of testing up to six radios and standards. The base model comes ready to test WiFi and Bluetooth?. GPS, FM, NFC, WiMAX can be added anytime via simple software licensing.
Reduce Test Time with Multi-Radio Concurrent Testing
Multi-radio devices are increasingly used in phones and other embedded applications. Traditional test approaches add test time with every connectivity standard added to the device. The IQ2011 enables up to 50% test time reduction with respect to traditional approaches. It does so by covering all key connectivity standards in one box, thus enabling one-insertion testing while testing multiple radios concurrently.
Optimize Capital Expenditures with Technology Software Licensing
The IQ2011 allows you to add as many capabilities as needed, whenever you need them. The IQ2011 can be purchased with WiFi and Bluetooth support only: additional technology standards can be added anytime via software licensing in the field. IQ2011’s licensable software platform allows you to adapt your test facilities to the changing needs of your multi-radio devices, without having to commit to capital equipment expenditures in advance.
Reduce WiFi Test Time with Sequence-Based Testing
The IQ2011 features proprietary, sequence-based test flow capability, which dramatically reduces WiFi test time for supported devices. In transmit multi-data-rate testing, the IQ2011 can sequence or step in concert with the device because the test system can capture signals at different data rates in a single capture. While performing a PER receive test, when packets are transmitted to the device, the IQ2011 uses specialized circuits to detect the acknowledgement signals from the device. These signals provide confirmation of the received data, and PER can be calculated without requiring extensive communication with the device, thus saving test time.
