LISTED UNDER:

VNAAnritsu Company expanded its VectorStar family of Vector Network Analyzers (VNAs) with the introduction of the MS4640B Series. Featuring a number of new cutting-edge measurement capabilities, including PulseView, which provides pulse profile, point-in-pulse and pulse-to-pulse measurements of S-parameters, and DifferentialView for true mode stimulus S-parameter measurements, this VNA helps engineers address the challenges associated with testing and characterizing components and sub-systems designed for radar and today’s high-speed serial applications. PulseView enables design engineers and component manufacturers in the aerospace and defense industry to accurately test and characterize designs under pulse conditions. The 2.5 ns resolution with 100 dB dynamic range, coupled with independent measurement gates, provides exceptional clarity of results. It also enables users to see performance perturbations on the rising/trailing edges and within a pulse that have been previously missed by other systems. A capture time of 500 ms permits users to measure under long pulse repetition interval conditions or to conduct pulse-to-pulse measurements over an extended number of pulses.

An additional, required, IF digitizer option provides fast digitization for the PulseView application, as well as four internal pulse generators. The pulse generators can be used to modulate devices under test (DUT) or one of a series of associated Modulation Test Sets also available. These features are complemented by a graphical interface that simplifies measurement setup and raises confidence that the user is measuring under the correct conditions. DifferentialView, together with an optional internal second source, provides engineers developing differential amplifiers or signal integrity engineers working on high-speed serial designs with the ability to evaluate their designs under true mode stimulus conditions.
