The MS4640B VectorStar VNA offers the broadest coverage in a single instrument, 70 kHz to 70 GHz. The additional two decades at the low end are even more impressive than the guaranteed 70 GHz coverage on the high end. PulseView™, when combined with the innovative IF digitizing option, offers industry-leading 2.5 ns pulse resolution and 100 dB dynamic range with no compromises or trade-offs due to varying duty cycles. PulseView provides real time display of pulse measurements while dynamically modifying pulse parameters for immediate design validation. DifferentialView™, when combined with the dual internal source option, offers real time display analysis of differential devices, drivers, and components while actively modifying phase and magnitude relationships of the internal dual sources.
