Agilent 8753ES Vector Network Analyzer Includes - Calibration Certificate The Agilent 8753ES vector network analyzer allows complete characterization of RF components. The 8753ES includes an integrated synthesized source, test set and tuned receiver. The built-in S-parameter test set provides a full range of magnitude and phase measurements in both the forward and reverse directions. Built-in vector accuracy enhancement techniques include full two-port calibration, adapter-removal and TRL*/LRM* calibration. The 8753ET/ES family includes both T/R and S-parameter test sets, covering 3 and 6 GHz.
