⭕ Anritsu MS4623B 10MHz to 6GHz Vector Network Analyzer Measurement System with Options 3B (2nd Internal Source, 3rd Test Port), 4 (Noise Figure Measurements), 10 (Internal Autocal), 11A (Replaces N female with GPC-7 male Test Port Adapters) and 13 (Intermodulation Distortion Measurements). The MS4623B is an instrument which measures the complex transmission and reflection characteristics of two-port devices in the frequency domain. 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. 14 day returns accepted and delivery available or collection local. Calibrated recently.
