What can a signal analyzer do?
480信号分析仪能够测量输入信号在单个频率上的幅度和相位。 信号分析仪将扫频调谐频谱分析仪的超大动态范围与矢量信号分析仪（VSA）的强大功能相结合，能够执行信道内测量，例如需要幅度和相位信息的误差矢量幅度（EVM）测量。 ,

频谱分析仪主要有两大类：扫频调谐分析仪和实时分析仪。 现代频谱分析仪采用了数字信号处理技术，可以提供更多的测量功能，使您可以更轻松地解读测量结果。 无论是扫频调谐分析仪还是实时频谱分析仪，它们均可显示幅度随频率的变化。 不过，每种分析仪具体是如何处理和显示此信息的呢？ 实时频谱分析仪可以同时显示所有频率分量的能量。 扫频调谐频谱分析仪则是按顺序显示测量结果，换句话说，它并非“实时”测量。 这是因为扫频调谐分析仪使用了一个窄滤波器，此滤波器在一个频率范围内进行调谐以生成频谱显示。

What is IQ modulation?
241In-phase quadrature modulation (IQ modulation) is the main modulation scheme used in communication applications. It is popular because of its efficient use of bandwidth, meeting the increasingly urgent need for bandwidth in a world where data volumes are growing exponentially. It is important to test with simulated IQ signals because designers are always faced with a lack of bandwidth in an interference-ridden spectrum. Example...
