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. Frequency is swept to rapidly obtain amplitude and phase information over a band of frequencies of interest. Anritsu 37347C network analyzers utilize synthesized-frequency sources to provide a known test stimulus that can sweep across a range of frequencies or power levels. Anritsu 37347C network analyzers also can perform ratioed measurements (including phase), which require multiple receivers. The Anritsu 37347C can provide a wealth of knowledge about a device under test (DUT), including its magnitude, phase, and group-delay response.
