The VectorStar ME7838x4 Broadband systems provide high performance 4-port measurements utilizing compact mmwave modules with industry-best calibration stability. While other broadband systems continue to provide raw performance with negative directivity in critical frequency bands, the ME7838 series, which includes the 4-port systems includes broadband systems with positive raw directivity. The result is better calibration stability and better measurement stability with significantly longer time between calibrations for accurate measurements and improved productivity. The new ME7838G4 takes high performance 4-port broadband measurements to a new level by incorporating the Anritsu MA25400A mmWave module. The MA25400A module combines Anritsu developed Nonlinear Transmission Line (NLTL) technology in a small, compact high performance mmWave module with a 0.6 mm test port connector for measurements up to 220 GHz.

Spectrum Analyzer Option

The spectrum analyzer option is the worlds 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.
