The two ShockLine MS46131A VNAs determine the instrument performance of the ME7869A, as they become the test
ports and provide the source and measurement capabilities for the 2-port VNA. The MS46131A is based on patented
ShockLine VNA on-chip technology, which simplifies the internal VNA architecture at high frequencies, reduces instrument
cost and size, and enhances accuracy and measurement repeatability.
The patented PhaseLync technology enables the multiple MS46131As to phase synchronize, enabling the ME7869A VNA to
measure complex S-parameters on passive RF and Microwave devices. The MS46131A-012/025/050/100 PhaseLync
options support synchronization to distances of up to 100 meters, enabling the ME7869A to simplify applications where
vector transmission measurements over distance is required by bringing the VNA port to the DUT.
The ME7869A VNA uses USB communication to control both MS46131A VNAs from an external PC. ShockLine software
runs the ME7869A as well as the rest of the ShockLine family of VNAs, providing a powerful graphical user interface for
debugging and manual testing of devices. The software also provides a common command syntax that is compatible
across the entire ShockLine VNA lineup for comprehensive remote control programming.
