ARMS, an Automated Measurement System for Broadband Modeling of Tx/Rx Devices for High-Fidelity RF Interference Analysis

In order to accurately predict RF interference (RFI) between multiple RF systems in complex environments, one must use high fidelity measured data. There are many ways that transmitters can interfere with receivers. The root cause of the interference is often not intuitive and the limited performance data provided by vendors makes developing accurate models a challenge. Manual measurements for transmitters and especially receivers can be very time consuming especially when considering radios that can operate over hundreds or thousands of channesl. This paper describes an Automated Radio Measurement System (ARMS) that can generate broadband models for transmitters and receivers allowing for accurate RFI analyses.
