Vector Network Analyzers (VNA)
MS4640B Series VectorStar Family of RF, µW, mmW VNAs
The Anritsu 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.
Key Features
- SPA available from 70 kHz to 20/40/70/110/125/145 and 220 GHz. Also available for banded configuration to 1.1 THz
- Dual SPA mode available: suitable for Mixers, Amplifier, Harmonics, and Spurious testing
- SPA available on all ports. User can define which port to use as SPA port
- Several detection types available in classical mode: Peak, Minimum, RMS, Mean
- Various math functions can be applied on SPA mode like Min hold, Max hold, and user-defined equations
- Sources and receivers can be independently configured; can be used as Tracking Generator
- For units with dual source, a dual drive option is available; support for external source control also possible
- Phase synchronization for units with dual source available, allowing control and configuration of phase between the two sources
- Source and receiver attenuator available with VNA can be activated in SPA mode; recommended to use option 62 (with attenuator on receiver side) for measuring the spectrum content of high-power devices
- Software option: easy to install and upgrade existing user equipment
