Microwave VNA Delivers Optimal Measurement Speed
Anritsu Company introduces its VectorStar premium series of microwave VNAs. The MS4640A delivers frequency coverage of 70 kHz to 70 GHz, dynamic range of 103 dB at 67 GHz and measurement speed of 20 µs/point. The product family offers 3 standard frequency ranges that go to 20, 40 and 70 GHz. This high-performance 2-port engine adds future capabilities, and it is compatible with existing four-port and broadband mmW systems for 70 kHz to 110 GHz measurements, or waveguide banded measurements up to 500 GHz. Applications are in traditional VNA markets that include aerospace/defense, satellite, commercial microwave communications, materials measurement and advanced research. For true broadband applications such as device modeling, the 70 kHz low-end provides seven octaves of additional information below the traditional 10 MHz cut-off of conventional microwave VNAs.
