簡(jiǎn)要描述;簡(jiǎn)介
帶有R＆S®CMW-Z11的R＆S®CMW-Z10具有出色的屏蔽效果和的耦合特性，R＆S®CMW-Z10可用于高達(dá)6 GHz的頻率。 這些出色的功能與模塊化選項(xiàng)概念相結(jié)合，使得RF屏蔽盒對(duì)于任何無(wú)線(xiàn)電通信測(cè)試儀都是*的。
射頻屏蔽盒由堅(jiān)固的鋁制成。 它通過(guò)一個(gè)具有限定擋塊的杠桿手柄牢固地關(guān)閉。 這確保了圍繞整個(gè)箱體提供的密封線(xiàn)的均勻壓縮。 蓋子內(nèi)襯吸收材料，可zui大限度地減少反射。
天線(xiàn)耦合器板上的天線(xiàn)結(jié)構(gòu)經(jīng)過(guò)優(yōu)化，可實(shí)現(xiàn)出色的無(wú)線(xiàn)連接。 高度寬帶螺旋天線(xiàn)可用于各種應(yīng)用。

特點(diǎn)與優(yōu)勢(shì)
寬頻率范圍高達(dá)6 GHz
帶R＆S®CMW-Z11的R＆S®CMW-Z10適用于高達(dá)6 GHz的應(yīng)用，因此涵蓋了GSM，UMTS，LTE，CDMA2000®，WLAN，Bluetooth®和GPS等所有常見(jiàn)無(wú)線(xiàn)標(biāo)準(zhǔn)。它提供了高屏蔽效能，使外部干擾的影響降至zui低。
超低的反射
RF屏蔽盒的蓋子襯有吸收材料以減少反射。作為DUT位置的函數(shù)，強(qiáng)反射會(huì)引起衰減的顯著變化。
模塊化選項(xiàng)概念和靈活的模塊分配
帶R＆S®CMW-Z11的R＆S®CMW-Z10具有四個(gè)用于不同可選模塊的模塊插槽?？捎玫倪x件目前包括25針D-Sub饋通（R＆S®CMW-Z12），USB 2.0饋通（R＆S®CMW-Z13），雙N連接器（R＆S®CMW-Z14）和15針D- Sub饋通（R＆S®CMW-Z15）用于雙向音頻測(cè)試。也可以插入客戶(hù)特定的模塊。
足夠的空間可以實(shí)現(xiàn)定位，即使對(duì)于諸如平板電腦等大型DUT也是如此
即使是大型DUT，例如平板電腦，也可以適應(yīng)。 RF屏蔽盒為定位DUT提供了充足的空間，可以zui大限度地減少DUT和測(cè)試儀之間的耦合衰減。
專(zhuān)為苛刻的，持續(xù)的工作和人體工程學(xué)操作而設(shè)計(jì)
射頻屏蔽盒設(shè)計(jì)可承受服務(wù)和制造環(huán)境中遇到的惡劣條件。關(guān)閉機(jī)構(gòu)經(jīng)過(guò)優(yōu)化，符合人體工程學(xué)使用，確保防疲勞操作，同時(shí)提供高質(zhì)量的結(jié)果。
天線(xiàn)分集和MIMO測(cè)試
R＆S®CMW-Z16第二個(gè)天線(xiàn)選件是圓極化的第二個(gè)天線(xiàn)元件，可以測(cè)試發(fā)射分集天線(xiàn)和多輸入多輸出（MIMO）系統(tǒng)。
R＆S®CMW-Z16安裝在射頻屏蔽盒的背面，可實(shí)現(xiàn)MIMO DUT（如LTE MIMO 2x2）的輻射耦合。標(biāo)準(zhǔn)天線(xiàn)向第二個(gè)天線(xiàn)元件（R＆S®CMW-Z16）提供90°方向的耦合場(chǎng)。這提供了近場(chǎng)環(huán)境中MIMO設(shè)備的耦合。
雙向音頻測(cè)試
R＆S®CMW-Z15音頻測(cè)量選件提供R＆S®CMW-Z10中雙向音頻測(cè)量所需的附件。音頻測(cè)量所需的麥克風(fēng)和揚(yáng)聲器可以地定位在RF屏蔽盒內(nèi)。音頻信號(hào)通過(guò)屏蔽D-Sub饋通傳輸，以zui大限度地減少外部干擾對(duì)屏蔽盒特性的影響。音頻信號(hào)通過(guò)RF接口傳輸?shù)綗o(wú)線(xiàn)電通信測(cè)試儀的音頻編碼/解碼器。音頻路徑可以通過(guò)比較原始信號(hào)和恢復(fù)的信號(hào)來(lái)測(cè)量。
