ME7868A Specifications
Introduction
The ME7868A is part of the ShockLine™ family of Vector Network Analyzers from Anritsu. It is a modular 2-port VNA
consisting of two ShockLine MS46131A 1-port VNAs synchronized with PhaseLync™ technology. The ShockLine ME7868A
2-port VNA is available in three frequency ranges: 1 MHz to 8/20/43.5 GHz, and is capable of S-parameter and time domain
measurements.
The two ShockLine MS46131A VNAs determine the instrument performance of the ME7868A 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. This makes the 1-port VNA an ideal platform on which to
create the distributed 2-port ME7868A VNA.
The patent-pending PhaseLync technology enables the two MS46131As to phase synchronize enabling the ME7868A to
measure complex 2-port S-parameters on passive RF and Microwave devices. The MS46131A-012 PhaseLync option
supports synchronization to distances of 100 meters or greater, enabling the ME7868A to simplify applications where
vector transmission measurements over distance is required by bringing the VNA port to the DUT.
The ME7868A VNA uses USB communication to control both MS46131A VNAs from an external PC. ShockLine software
runs the ME7868A 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.
This document provides detailed specifications for the ME7868A series Vector Network Analyzers and related options.
