Anritsu’s ShockLine ME7869A provides remote vector measurements

  • Anritsu introduces the ShockLine ME7869A distributed modular 2-port vector network analyzers (VNAs) that can conduct long-distance full vector S-parameter measurements over distances of up to 100 meters.
  • This solution can implement VNA modules covering frequencies of 8 GHz, 20 GHz and 43.5 GHz, depending on the model.

The ME7869A is configured with two MS46131A 1-port VNAs that can each be directly connected to the antenna under test. Cable length for each VNA module can be equal or different lengths, depending on the application. It eliminates the need for long RF coaxial cables that create high loss, and phase and magnitude instability.

This solution addresses the need to accurately and repeatably measure antennas over long distances, such as in anechoic chambers and antenna test ranges.

Anritsu’s PhaseLync synchronization technology enables two MS46131A VNAs to phase synchronize with each other over a 100-meter distance. PhaseLync improves dynamic range and measurement stability of S-parameter measurements by eliminating the need for long cables necessary with conventional benchtop VNAs.

Another key benefit of the distributed modular VNA solution is the MN25132A control module, which simplifies installation. It acts as a junction for the cables and supplies power to the two MS46131A VNAs. There is no need to attach separate power supplies to the two VNA heads. The control module also interfaces the two VNAs to a laptop configured with ShockLine software.

The ShockLine ME7869A can be use for any insertion loss application that requires long cable runs at frequencies up to 43.5 GHz.
