RF 信號發(fā)生器常見問題

RF 信號發(fā)生器的用途是什么？

RF-Signal-Generator

射頻 (RF) 信號發(fā)生器用于創(chuàng)建具有已知特性的連續(xù)射頻信號，以測試電路設(shè)計，主要是通信設(shè)備中的電路設(shè)計。RF 信號發(fā)生器本身不進(jìn)行任何測量，它只是為其他儀器設(shè)置正確的條件來測量被測設(shè)備。

RF 發(fā)生器如何工作？

RF 信號發(fā)生器通常是一種信號源，用于測試開發(fā)用于 RF 通信（例如無線和蜂窩通信、雷達(dá)、電子戰(zhàn)等）的電路。工程師可以使用系統(tǒng)控制設(shè)置幅度、頻率并對信號應(yīng)用調(diào)制。

如何生成 RF 頻率？

生成 RF 頻率的簡單方法是使用 TSG4100A RF 信號發(fā)生器的前面板。在將 RF 信號發(fā)生器連接至被測設(shè)備 (DUT) 前，您可以輕松設(shè)置頻率、幅度、調(diào)制和許多其他信號特性。

信號發(fā)生器和函數(shù)發(fā)生器有何區(qū)別？

信號發(fā)生器是任何產(chǎn)生電子信號的設(shè)備。矢量信號發(fā)生器專門使用模擬和數(shù)字調(diào)制方案以 QAM、QPSK、FSK、BPSK 和 OFDM 等格式創(chuàng)建射頻信號。矢量信號發(fā)生器通常用于接收機(jī)靈敏度測試。

函數(shù)發(fā)生器具有其可播放的預(yù)設(shè)波形或模式列表。操作員可以更改波形參數(shù)，例如播放速度、幅度和偏置，或添加基本失真或調(diào)制。

信號發(fā)生器的類型有哪些？

信號發(fā)生器的類型有很多，包括函數(shù)發(fā)生器、任意波形發(fā)生器和矢量信號發(fā)生器。

查看下表了解每種類型之間的差異。

信號發(fā)生器	模擬和數(shù)字電子信號源的通用類別名稱。
函數(shù)發(fā)生器	如需正弦波、三角波等常見波形，則通常使用信號發(fā)生器。
任意函數(shù)發(fā)生器	函數(shù)發(fā)生器能夠產(chǎn)生任意編譯波形。
任意波形發(fā)生器	如需自定義編譯波形（而不是預(yù)設(shè)常用波形），則主要使用任意波形發(fā)生器。
RF 信號發(fā)生器	RF 信號發(fā)生器用于無線應(yīng)用，通常提供正常的模擬調(diào)制，例如 AM、FM 和 PM。
(RF) 矢量信號發(fā)生器	對于數(shù)字通信應(yīng)用，RF 矢量信號發(fā)生器支持對 RF 載波進(jìn)行模擬和矢量調(diào)制。
