VectorStar offers a performance benchmark for S-parameter measurements of RF, microwave and millimeter-wave devices providing engineers access to a powerful measurement tool for performance analysis.
 
The VectorStar™ family is Anritsu's Premium VNA line, providing the highest overall performance on a modern platform. 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.
Instrument Models and Operating Frequencies
MS4642B – (Optional 70 kHz) 10 MHz to 20 GHz
MS4644B – (Optional 70 kHz) 10 MHz to 40 GHz
MS4647B – (Optional 70 kHz) 10 MHz to 70 GHz
 
IMDView™
Provides active menu sidebar with real time measurement display while modifying critical IMD parameters. The internal combiner option offers single connection testing of active devices for automatically switching between S parameter and IMD measurements without the need for reconnecting the DUT.
 
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.
 
Spectrum Analyzer Option
 
The spectrum analyzer option is the world’s first single sweep spectrum analyzer that covers frequency ranges from 70KHz to 220GHz using mm-wave modules. The Spectrum analyzer option is available on all baseband VectorStar models.
 
The Spectrum Analyzer option (Option 49) allows for convenient spectral domain measurements of quantities such as harmonics, spurs, distortion products, and general frequency content of a variety of devices. Common measurements include harmonics, tone-based distortion measurements, some spurious measurements, and spectral occupancy tests on devices that may include multiple outputs or input-output comparisons.
 
The noise figure option is based on a cold source technique for improved noise figure measurement accuracy. VectorStar is the only VNA platform capable of measuring noise figure from 70 kHz to 125 GHz and available with an optimized noise receiver for measurements from 30 GHz to 125 GHz. Additionally, VectorStar is the only VNA that offers a Differential Noise Figure option for characterizing the noise figure of differential devices.
 
For broadband applications, the ME7838 Series offers superior performance and coverage spanning a range from 70 kHz to 110 GHz, 125 GHz and 145 GHz in a single coaxial test port. The Anritsu developed Non-linear Transmission Line mmWave module is compact while providing high performance up to 145 GHz.
The Anritsu MS4640B Vector Network Analyzer offers a new level of performance for device modeling engineers struggling to accurately and reliably characterize their devices, for R&D engineers pushing the last fraction of a dB out of their state-of-the-art designs, and for the manufacturing engineer trying to maximize throughput without sacrificing accuracy. Backed by a 3-year warranty and the most responsive sales support team, the MS4640B is the VNA of choice for the discerning engineer.
