Overview
The Anritsu MS46644A is the 4-port, 10 MHz to 43.5 GHz model of the Tensor MS466xxA vector network analyzer family. It is designed for characterizing passive and active devices as well as frequency-translating devices such as mixers.
The Tensor architecture provides a dedicated source for each port, with independent control of multiple sources and receivers, and is built for high-speed data acquisition and transfer. Hardware options across the family include direct access loops, receive-side and source-side step attenuators, a second internal local oscillator (LO) on four-port instruments, external ALC, external IF in and out, and banded mmWave support. Software options include time domain processing, gain compression, several mixer measurement options and mmWave support.
AI-assisted measurement setup
Tensor includes AI-assisted measurement workflows that let users configure complex measurements through natural language interaction. On request, the system presents the setup details for a measurement such as a mixer test, including a block diagram, recommended connections and settings. Once sufficient information is provided, it configures the measurement, performs the required calibrations and executes the test. The AI engine runs on the instrument itself and does not require an Internet connection.
