在應(yīng)用和生產(chǎn)中提供一流的靈活性
SMCV100B矢量信號(hào)發(fā)生器率先成為適用于汽車(chē)電子、廣播電視、導(dǎo)航和無(wú)線(xiàn)應(yīng)用的多標(biāo)準(zhǔn)平臺(tái)。R&S?SMCV100B 功能獨(dú)特，可用于從實(shí)驗(yàn)室到生產(chǎn)以及整合不同技術(shù)的多種應(yīng)用。
主要特點(diǎn)：
• 適用于廣播電視、導(dǎo)航、蜂窩和無(wú)線(xiàn)應(yīng)用的多標(biāo)準(zhǔn)平臺(tái)
• 全軟件選件定義的矢量信號(hào)發(fā)生器，具備5"觸摸屏
• 先進(jìn)的射頻信號(hào)生成概念，頻率范圍介于4kHz至7.125GHz
• 輸出功率高達(dá)+25dBm
• 調(diào)制帶寬高達(dá)240MHz
產(chǎn)品優(yōu)勢(shì)：
創(chuàng)新性&穩(wěn)定性
頻率產(chǎn)生單元，作為信號(hào)發(fā)生器的基礎(chǔ)和核心，自然而然成為工程師們大開(kāi)腦洞的首要對(duì)象。
今天，得益于半導(dǎo)體技術(shù)的不斷進(jìn)步，直接合成+混頻架構(gòu)的出現(xiàn)，讓模數(shù)概念又有了新的玩法。
SMCV100B采用最新的直接數(shù)字射頻上變頻技術(shù)來(lái)生成頻率高達(dá)2.5GHz的輸出信號(hào)。這允許在數(shù)字域中進(jìn)行I/Q調(diào)制和RF信號(hào)生成，消除了傳統(tǒng)模擬I/Q調(diào)制器常見(jiàn)的I/Q不平衡誤差和LO泄漏。由于有了新概念，信號(hào)發(fā)生器的SSB相位噪聲性能非常好。模擬混頻概念用于生成2.5GHz以上的頻率。
品質(zhì)保證&性?xún)r(jià)比
SMCV100B是第一款能夠涵蓋5GNRFR1到7.125GHz的經(jīng)濟(jì)型信號(hào)發(fā)生器，這也使其成為移動(dòng)通信應(yīng)用的理想選擇。 SMCV100B還可以使用 WinIQSIM2仿真軟件，該軟件支持所有常見(jiàn)的蜂窩和無(wú)線(xiàn)連接標(biāo)準(zhǔn)，包括IoT和Wi-Fi（802.11xx）等標(biāo)準(zhǔn)。
作為享譽(yù)業(yè)界的射頻專(zhuān)家，R&S將在射頻設(shè)計(jì)和信號(hào)分析能力表現(xiàn)出的一流的價(jià)值和出色的可靠性，繼續(xù)發(fā)揚(yáng)在 SMCV100B身上，完美支撐起新架構(gòu)"直接數(shù)字合成"的技術(shù)優(yōu)勢(shì)。
SMCV100B是優(yōu)化現(xiàn)有測(cè)試系統(tǒng)的理想解決方案。生產(chǎn)部門(mén)通常都需要最大程度的靈活性和極快的響應(yīng)時(shí)間，以生成不同標(biāo)準(zhǔn)的信號(hào)。憑借其平臺(tái)概念， SMCV100B可以完全滿(mǎn)足這些要求，之前用于不同標(biāo)準(zhǔn)的多個(gè)信號(hào)源現(xiàn)在只需一臺(tái) SMCV100B即可代替，為未來(lái)測(cè)試系統(tǒng)的擴(kuò)展實(shí)現(xiàn)成本控制。
硬實(shí)力&軟實(shí)力
更為關(guān)鍵的是， SMCV100B并不"偏科"，不管是在硬件上，還是軟件系統(tǒng)方面，都已經(jīng)達(dá)到了一個(gè)新的高度。
SMCV100B為內(nèi)部基帶信號(hào)生成提供了強(qiáng)大的硬件。它可以在FPGA中實(shí)時(shí)生成信號(hào)，也可以使用ARB發(fā)生器直接生成用于數(shù)字通信標(biāo)準(zhǔn)的I/Q信號(hào)。
FPGA中的實(shí)時(shí)信號(hào)生成專(zhuān)用于廣播標(biāo)準(zhǔn)。這種技術(shù)能夠連續(xù)和長(zhǎng)時(shí)間不間斷地生成用于解碼的不同數(shù)據(jù)內(nèi)容（音頻、視頻、數(shù)據(jù)、PRBS）的信號(hào)。這樣的長(zhǎng)序列對(duì)于測(cè)試調(diào)諧器的性能或EMC是必需的。
