The Anritsu MS4640A 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.
Anritsu's MS4640A 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, for better device modeling without having to switch to another RF VNA. The industry leading 100 dB dynamic range at 70 GHz, coupled with excellent raw performance, will offer the best accuracy and stability to the toughest measurements. And when you can achieve synthesized sweeps at the industry fastest 20 µs/point, while achieving greater than 80dB sensitivity, the result is the best all-around VNA available on the market today, and for a long time to come.
Anritsu's VNA is destined to become the ideal microwave VNA platform, built on an Open Windows architecture, with unlimited potential such as 100,001 points in single channel mode, with versatile connectivity, and intuitive interface. Backed by the industry's first standard 3-year warranty and the most responsive sales support team, the MS4640A is the VNA of choice for the discerning engineer.
Option 041 – Noise Figure adds the capability to measure noise figure, which is the degradation of the signal-to-noise ratio caused by components in a signal chain. The noise figure measurement is based on a cold source technique for improved accuracy. Various levels of match and fixture correction are available for additional enhancement. VectorStar is the only VNA platform capable of measuring NF from 70 kHz to 125 GHz and available with an optimized noise receiver for measurements from 30 GHz to 125 GHz.
