轻松生成RF 信号

越来越复杂的RF 信号，使RF 工程师准确生成标准测试或余量测试要求的信号变得越来越难。为迎接这一设计挑战，泰克RFXpress提供了高级RF/IF/IQ生成和编辑工具。RFXpress 是一套以数字方式合成被调制基带信号、IF 信号和RF 信号的软件包，通过全面利用泰克任意波形发生器(AWG)的宽带信号生成功能，把信号生成能力提升到全新的水平。该软件支持广泛的调制方案，允许用户使用各种标准的调制和跳频方式产生标准波形，同时用户也可自己定制波形。在"Auto Mode"下，该软件可以自动计算从任意波形发生器中输出所生成信号需要的波形长度(单位为样点数或符号数)及采样率。RFXpress 还包括一种校准功能，可以完成信号预失真，从而保证AWG输出信号的平坦幅度和线性相位响应。通过RFXpress，用户还可以简便地复现泰克示波器采集的波形(*.wfm)及实时频谱分析仪保存的IQ波形(*.iqt, *.tiq)。然后可以增加损伤、失真或干扰，全面地完成设计极限测试。

UWB-WiMedia (UWBCF/UWBCT)是RFXpress的一个软件模块，能够在UWB频谱中以数字方式合成和生成信号。根据最新的WiMedia 规范，该软件模块可以重建1.5 GHz 调制带宽中实时跳频要求的信号。UWBCF/UWBCT使得用户可以全面控制WiMedia 信号特点，包括所有频段组中的前置码同步顺序、封装顺序、TFC。可以在IQ 信号、IF 信号或直接RF信号中生成全部六个频段组(BG1-BG6)，为用户创建/上变频信号提供了三种不同的选项。该软件以两种模式工作：在标准模式(UWBCF)下，用户可以生成符合最新版WiMedia 规范的标准波形；在自定义模式(UWBCT)下，用户可以调节信号包头或净荷的任意部分，执行极限和余量测试。

RFXpress雷达信号生成软件模块为生成脉冲式雷达波形提供了最高的灵活性。用户可以从脉冲到脉冲串、再到脉冲组，创建成套的自定义雷达脉冲。它支持各种调制方案，包括LFM、巴克码和多相码、用户自定义代码、步进调频、非线性调频、用户自定义步进调频和自定义调制。它还能够生成参差PRI的脉冲串，解决距离和多普勒模糊问题；生成电子对抗(ECCM)的跳频信号和脉冲到脉冲幅度变化，仿真Swerling 标靶模型。

RFXpress 在PC 上运行，或作为泰克AWG5000/AWG5000B 和AWG7000/AWG7000B系列任意波形发生器的内置部分运行。
