Two-port VNA family combines performance and cost efficiencies

Anritsu has launched the ShockLine ME7868A family of modular two-port VNAs that can conduct full vector S-parameter measurements over extensive distances of up to 100m. Comprises of two MS46131A one-port VNAs with the PhaseLync synchronisation option hardware and accessories, the ME7868A VNA utilises the MS46131As as portable VNA ports to directly connect to the DUT to produce vector transmission measurements over longer lengths and at a lower cost. The VNAs provide multiple advantages when compared to traditional solutions that employ two-port VNAs with very high dynamic range and need long and costly phase-stable microwave cables to reach the DUT.

Offered in 8GHz, 20GHz, and 43.5GHz frequency models, the series supports multiple existing and emerging commercial and defence applications, including high-frequency 5G. As the first modular-port-based VNA, the device removes the requirement for long port cables to measure transmission over distance for applications covering outdoor antenna range testing, OTA chamber installations, large vehicle (aircraft, ship) electromagnetic characterisation (shielding, RF propagation), and long-distance cable insertion loss measurements.

Extremely lightweight and remarkably compact, the two MS46131A one-port VNAs that comprise the device are USB controlled through an external PC running ShockLine software. Engineers can simply configure and control the VNAs from a single PC to conveniently match port count to test setup necessities. Data is more secure, as all measurement results are stored on the PC, rather than the VNA, making the solution ideal for confidential testing environments.

Analysis and documentation are also simplified, as there is no requirement to transfer data off the onboard instrument memory.
