    HIGHLIGHTS

    • Spectrasys——频谱域射频系统体系结构仿真器,与电路工具、用于时域仿真器的数学功能模块组、厂商的“计算器”应用程序和电子表格相比,其优势在于能够提供引人注目的仿真和交互式图形使用模型。用户可以选择数十种预先编程的测量,并直接与图形进行交互
    • 射频链路——快速、自动化的数据流程建模工具,可以执行系统级数据流程仿真,无需进行修改即可直接使用频域 Spectrasys 框图。它将多级上下变频、频谱反转、多个 I/O 端口、基带或调制载波端口、热噪声和相位噪声频谱密度,以及频段内的频率和功率相关性都考虑在内
    • ADS X 参数*支持——在系统级使用电路级非线性 X 参数,自下而上地迅速验证 ADS 设计或厂商测得的器件特征。它将复杂的阻抗负载效应、谐波、偏置、功率和频率相关性都考虑在内。支持新式 Volterra 建模,为多音频大信号仿真提供更准确的单音频 X 参数数据
    • GoldenGate“快速电路包络”模型――对多达 1,000-100,000 个无线 SoC/RFIC 收发信机进行系统级验证的速度比 Spice 更快,同时将频率转换、频率和功率相关性以及记忆效应都考虑在内。具有足够快的速度,能够在 Keysight 89600B VSA 上运行编码的 LTE BER/吞吐量仿真或即时解码、
    • WhatIF——用于多频段无线前端的射频频率规划实用程序

    SystemVue ESL Design SoftwareW1719 射频系统设计套件为射频系统架构师以及参与射频电路和系统设计的物理层级设计人员提供创新的仿真器和使用模型。W1719 是 SystemVue 环境的一个选件,可以弥合两类设计人员在设计流程上的鸿沟:

    • RF System Architects: The W1719 helps create better RF systems, lowers project risk, and saves time and prototyping costs by quickly diagnosing RF/Analog effects that are difficult or impossible to characterize with spreadsheets and other analysis techniques. As an RF architecture tool, it also closes the verification loop by connecting implementation-based models from Advanced Design System (ADS) and GoldenGate to Baseband algorithms, Reference IP, and test equipment, for superior RF-DSP partitioning and model-based verification.
    • 基带算法和系统级物理层架构师:W1719 提供易于使用的射频设计流程桥,它不仅精确、快速,而且不会影响 SystemVue 作为多语言建模环境的通用性。它使基带和系统级设计人员能够充分利用在真实晶体管级实施基础上建立的精确模型,无需全面了解整个射频领域的知识,也无需使用相关的射频工具和许可证。他们能够简单和自信地在数据流程中使用射频模型,并能使用通用工具包与其他领域的同行交换结果

    W1719 提供企业级射频设计流程才具备的射频精度、故障诊断功能和超快的建模链接,帮助系统架构师减少在设计当今复杂的无线和国防系统时所留下的过多裕量,而不会增加项目风险。它对于需要高线性度、宽带宽和深度算法复杂性的物理层系统是必不可少的。

    The W1719 now brings RF modulation effects inside the RF system architecture tool

    图 1. W1719 现在在射频系统体系结构工具中提供了射频调制效果,使宽带通信设计人员能够识别各种错误(例如非线性、相位噪声和滤波器平坦度)的来源。

    SystemVue W1719 RF System Design Kit

    图 2. W1719 将快速非线性 X 参数(ADS)和快速电路包络模型(GoldenGate)引入数据流程环境,以便对整个物理层(包括基带算法)进行系统级验证。

    SystemVue W1719 RF System Design Kit Flow

    图 3. W1719 射频系统设计套件是 SystemVue 的可选附件,与仅使用数据流程仿真器相比,它能够提供更深入的洞察力以及更出色的射频设计流程连通性。

    Spectrasys——为射频架构师提供模块级射频仿真器

    射频系统设计套件通过考虑模拟效应并提供对射频系统性能的一键式图形诊断,可为射频系统架构师节省时间。关键在于 Spectrasys 仿真器。

    Spectrasys 克服了电子表格、数学功能和 DSP 引擎、电路仿真器以及有限模型组的重要限制,后者要么完全忽视了模拟效应,要么使问题难以隔离和诊断。在确定频率规划、电路板面积、版图、物料清单和性能等指标之前,Spectrasys 使射频系统设计师能够在设计初期识别并修正欠佳的体系结构选择。

    它为设计人员提供了 100 多种预定义的系统测量和几十种基于功率和电压的特性模型,使他们不必花费时间编写自用代码,直接使用专为射频系统设计任务设计的专用图形工具,从而快速生成高质量的设计,缩短原型设计周期,减少高昂的故障诊断开支以及降低项目风险。

    SystemVue W1719 RF System Design Kit 图 4. Spectrasys 将复杂的失配、双向传播、非线性、频率响应、泄漏期限、从直流到毫米波的连续频谱都考虑在内,并跟踪各个信号和噪声来源。用户可以直接从图形中交互式地检查这些特性,检查过程只需短短几秒。

    WhatIF——射频频率规划器

    W1719 还提供“WhatIF” 频率规划工具。WhatIF 帮助无线系统架构师选择合适的中频(IF)组,从而利最少的滤波和设计裕量使用多频段射频接收机的系统性能达到最高。它采用交互式的图形化方法,使原本需要数周时间的分析工作在半天内即可完成。它可以将调谐带宽、杂散和互调频率考虑在内。

    W1719 Image

    图 5. WhatIF 频率规划工具可快速显示中频频率的最佳选择,以便实现卓越的无杂散性能并降低系统复杂程度。

    与 Genesys Spectrasys 对比

    作为 W1719 的功能之一,基础版 Spectrasys 仿真器和 WhatIF 实用程序也可作为 Keysight Genesys 环境的选件提供。如果您主要设计模拟/射频电路,能够使用 CW 音频获得近似的性能,或者信号处理内容很少,那么推荐您选择 Spectrasys 和 WhatIF 的 Genesys 版本。Genesys 配置见 Genesys 产品结构和选件摘要。

    如果您的通信或防御系统包含射频和信号处理内容,需要进行调制分析(如 EVM、BER、频谱再生或相控阵波束赋形),或者您需要连接到测试设备、无线标准参考,或是需要进行交互式基带建模,那么 SystemVue 中的 W1719 射频系统设计套件是当然之选。

    配置

    W1719 射频系统设计套件可添加至任意 SystemVue环境。

    W1719 包含在以下软件套件中:

    • W1464 SystemVue RF System Architect
    • W1465 SystemVue System Architect
    • W1467 SystemVue Array Architect

    对本产品感兴趣的功率放大器设计人员也可能对 W1716 SystemVue Digital Pre-Distortion Builder 感兴趣。
