General Information
Introduction
Option 015 Accessory Kit has been assembled to ensure that you have the necessary
accessories to set up return loss and loss/gain measurements. These accessories can be used to
make measurements with the PSA using option 215. The option 215 software allows you to
synchronize the tracking between an external source and the spectrum analyzer.
Because your device under test and system configuration are unique, you must provide any
additional connectors, adaptors, and cables to make the final connections to your equipment.
This document describes common measurement and normalization configurations for these
measurements. For more information about measurements and normalization, refer to the
External Source Control Personality Guide PSA Series Spectrum Analyzers Option 215.
