Anritsu introduces the ShockLine ME7868A family of modular 2-port vector network analysers (VNAs), which can conduct full vector S-parameter measurements over wide distances of up to 100 m.

Consisting of two MS46131A 1-port VNAs with the PhaseLync synchronisation option hardware and accessories, the ME7868A VNA uses the MS46131As as portable VNA ports to directly connect to the device under test (DUT). Delivering vector transmission measurements over long lengths, the VNAs offer multiple advantages compared to traditional solutions that use 2-port VNAs with high dynamic range and require long phase-stable microwave cables to reach the DUT.

Available in 8, 20 and 43.5 GHz frequency models, the series supports multiple existing and emerging commercial and military applications, including high-frequency 5G. As a modular-port-based VNA, the ME7868A eliminates the need for long port cables to measure transmission over distance for applications such as outdoor antenna range testing, over-the-air (OTA) chamber installations, large vehicle (aircraft, ship) electromagnetic characterisation (shielding, RF propagation) and long-distance cable insertion loss measurements.

PhaseLync technology enables two MS46131A 1-port VNAs to phase synchronise with each other over a distance of up to 100 m. PhaseLync improves dynamic range and measurement stability of s-parameter measurements by eliminating the need for long cables with conventional benchtop VNAs. The result is greater operational efficiencies when measuring transmission over distance.

Lightweight and compact, the two MS46131A 1-port VNAs that comprise the ME7868A are USB controlled via an external PC running ShockLine software. Engineers can easily configure and control MS46131A VNAs from a single PC to conveniently match port count to test set-up requirements. Data is more secure as all measurement results are stored on the PC, rather than the VNA, making the solution suitable for confidential testing environments. Analysis and documentation are also simplified, as there is no need to transfer data off the onboard instrument memory.
