Anritsu ME786xA Distributed Modular 2-Port VNA Capable of Making Vector Corrected 2-port S-parameter Measurements Over Longer Distances.

The ShockLine ME7869A 2-port systems are uniquely configured with two 1-port MS46131A VNAs that are synchronized together to form a fully reversing VNA.
Using patented PhaseLync synchronization technology, the 1-port VNAs are phase synchronized over a distance of up to 100 meters to enable full 2-port vector S-parameter measurements. This architecture eliminates the need for long cables by bringing the

VNA port to the device-under-test (DUT). This simplifies and improves the S-parameter measurements over distances in applications like over-the-air (OTA) and large vehicle shielding and propagation testing.

The ShockLine ME7869A is offered in 8 GHz, 20 GHz, and 43.5 GHz frequencies, and requires cabling between the two ShockLine MS46131A VNAs to support the PhaseLync option to support distances of up to 100 meters between the two ports of the VNA.

ShockLine Compact VNA Highlights

  • Portable and remote ShockLine ME7869A VNA ports eliminate long cables by bringing the VNA to the DUT, improving measurement stability and dynamic range
  • PhaseLync technology enables vector corrected magnitude and phase measurements between two ShockLine MS46131A VNAs separated by up to 100 meters
