矢量网络分析仪 (VNA) 包含源信号和接收机。接收机根据输入到设备（或网络）的源信号，检测设备输出信号的变化。矢量网络分析仪比较设备如何影响电流和电压，进而测量设备引起的幅度和相位响应。结果包括传输测量（传输系数、插入损耗、增益）、反射测量（反射系数、电压驻波比、回波损耗）、阻抗和散射参数（S 参数）S11、S12、S21 和 S22。
矢量网络分析仪是最重要的射频和微波测量工具之一，能够提供传输测量（传输系数、插入损耗、增益）、反射测量（反射系数、电压驻波比、回波损耗）、阻抗和散射参数（S 参数）S11、S12、S21 和 S22，因此适用于分析滤波器、天线或功率放大器等各种无源和有源器件。频谱或信号分析仪无法执行这些测量，因此需要在设计流程和生产流程的质量控制环节使用矢量网络分析仪。
应根据相应用例选择合适的仪器，罗德与施瓦茨提供广泛的网络分析仪，可满足各种使用要求。一般的选择标准包括频率范围；所需端口的数量，通常为 2 至 24 个（多端口），开关矩阵中甚至支持 48 个端口；输出功率；仪器等级，包括经济型、手持式和高端仪器。
矢量网络分析仪和频谱分析仪都使用射频接收机分析被测设备输出的射频信号。但是，矢量网络分析仪还额外生成校准后的射频激励信号并用作被测设备的输入信号，然后分析被测设备对这种激励行为的响应。相较于频谱分析仪，矢量网络分析仪能够测量不同的电气特性。
标量网络分析仪仅测量幅度特性，而矢量网络分析仪还可以分析相位特性。与矢量网络分析仪相比，标量网络分析仪更加简单，一般包括跟踪源和频谱分析仪，并可分析扫频测量幅度（振幅）。
此外，矢量网络分析仪可以采用更精密的校准程序，因此具有更出色的灵活性和准确性。
矢量网络分析仪 (VNA) 可用于测量无法使用其他射频测量工具的完整设备。矢量网络分析仪能够针对设备对信号的影响执行传输测量（传输系数、插入损耗、增益）、反射测量（反射系数、电压驻波比、回波损耗）、阻抗测量和散射参数（S 参数）S11、S12、S21 和 S22 测量。分析仪为射频网络或被测设备提供校准后的激励信号，并使用接收机以矢量-频率的形式测量包含相位和幅度信息的响应。
