Overview
The ME7869A-020 is the 20 GHz configuration of the Anritsu ShockLine ME7869A modular 2-port vector network analyzer. The system consists of two ShockLine MS46131A 1-port VNAs synchronized with PhaseLync technology and an MN25132A 2-port PhaseLync control module, and covers 1 MHz to 20 GHz for S-parameter and time domain measurements.
The two MS46131A VNAs act as the test ports and provide the source and measurement capabilities of the 2-port system. PhaseLync phase-synchronizes the modules so that complex S-parameters of passive RF and microwave devices can be measured. With the MS46131A-025, -050 or -100 PhaseLync length options, the ports can be synchronized over distances of up to 100 meters, allowing the VNA ports to be placed directly at the device under test instead of using long cable runs from a benchtop analyzer.
Software and control
Both MS46131A modules are controlled over USB from an external PC running ShockLine software, which is common to the ShockLine VNA family and provides a graphical user interface for debugging and manual testing as well as a common command syntax for remote programming. The VNA port configuration (single 1-port, dual 1-ports or single 2-port) can be set session by session. Because the units have no on-board data storage, there is no data to purge in secure applications.
The optional MS46131A-002 time domain capability with time gating, enabled on both modules, adds low-pass and band-pass time domain modes for characterizing discontinuities.
