Vector network analysers can measure vector S-parameters at up to 100m, says Anritsu

The ShockLine ME7868A two-port vector network analyser (VNAs) can deliver phase synchronised measurements and conduct full vector S-parameter measurements at up to 100ms, says Anritsu.

Two MS46131A 1-port VNAs with the PhaseLync synchronisation option hardware and accessories make up the ME7868A VNA. It uses the MS46131As as portable VNA ports to directly connect to the device under test (DUT) to deliver vector transmission measurements over longer lengths and at a lower cost, explains Anritsu. The VNAs offer multiple advantages compared to typical configurations that use two-port VNAs with very high dynamic range and require long and expensive phase stable microwave cables to reach the DUT.

Available in 8.0, 20 and 43.5GHz frequency models, the ME7868A series supports multiple existing and emerging commercial and military applications, including high frequency 5G. According to Anritsu, the ME7868A is the first modular-port-based VNA and it 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.

The new PhaseLync technology enables two MS46131A one-port VNAs to phase synchronise with each other over a distance of up to 100 m for the first time. PhaseLync improves dynamic range and measurement stability of S-parameter measurements by eliminating the need for long cables with conventional benchtop VNAs. This results in both cost and operational efficiencies when measuring transmission over distance.

The MS46131A one-port VNAs are lightweight and compact and are USB-controlled via an external PC running ShockLine software. Engineers can configure and control MS46131A VNAs from a single PC to match port count to test setup requirements. All measurement results are stored on the PC, rather than the VNA, to increase data security, adds Anritsu.

Analysis and documentation are simplified, says Anritsu, as there is no need to transfer data off the onboard instrument memory.

Anritsu engages customers as partners to help develop wireless, optical, microwave/RF, and digital solutions for R&D, manufacturing, installation, and maintenance applications, as well as service assurance for network monitoring and optimisation. Anritsu also provides precision microwave/RF components, optical devices, and high-speed electrical devices for communication products and systems. The company develops solutions for 5G, M2M, IoT, as well as other emerging and legacy wireline and wireless communication markets.
