Anritsu Option 51, Direct Access Loops
The MS4647B-051 is an official option for the Anritsu VectorStar MS4647B Vector Network Analyzer. Option 51, known as Direct Access Loops, provides direct access to the internal measurement loops of the instrument. This feature is designed to facilitate advanced measurement configurations, custom test setups, and integration with external test equipment. It is particularly useful for users who require enhanced flexibility for research and development, calibration, or specialized measurement applications. The Direct Access Loops option is factory-installed and must be specified at the time of order. It is compatible exclusively with the MS4647B model and is supported by Anritsus official documentation.
