Anritsu Option 31, Dual Source
The MS4642B-031 is Option 31 for the Anritsu VectorStar MS4642B Vector Network Analyzer, providing a dual source capability. This option enables the analyzer to generate two independent, phase-coherent sources, which is essential for advanced measurement applications such as mixer and frequency converter characterization, intermodulation distortion (IMD) measurements, and differential device testing. The dual source configuration enhances measurement flexibility and accuracy by allowing simultaneous stimulus of multiple ports or frequencies. This option is designed and supported by Anritsu for use exclusively with the MS4642B mainframe.
