The Anritsu MS4661A network analyzer is an instrument which measures the complex transmission and reflection characteristics of two-port devices in the frequency domain.该安立ms4661a网络分析仪是一种手段，用以测量复杂的透射和反射特性的双端口器件在频域。 It does this by sampling the incident signal, separating the transmitted and reflected waves, and then performing ratios that are directly related to the reflection and transmission coefficients of the two-port.这本由采样事件信号，政企分开转发和反射波，然后表演比率，是直接关系到反射和透射系数的两个港口。 Frequency is swept to rapidly obtain amplitude and phase information over a band of frequencies of interest.频率是席卷迅速获得振幅和相位信息超过波段的频率的利益。
Anritsu MS4661A network analyzers utilize synthesized-frequency sources to provide a known test stimulus that can sweep across a range of frequencies or power levels.安立ms4661a网络分析仪，利用合成频率源，以提供一个已知的测试刺激能横扫整个一系列的频率或功率水平。 Anritsu MS4661A network analyzers also can perform ratioed measurements (including phase), which require multiple receivers.安立ms4661a网络分析仪，也可以演出ratioed测量（包括阶段） ，这就需要多个接收器。 The Anritsu MS4661A can provide a wealth of knowledge about a device under test (DUT), including its magnitude, phase, and group-delay response.该安立ms4661a可以提供丰富的知识，对设备进行测试（ dut ） ，包括其幅度，相位和群延迟响应。
