This white paper emphasizes the pivotal role of Keysight Spectrum Management Software (KSMS) as a comprehensive software toolkit designed to revolutionize the management of frequency resources by frequency regulators, public and private network operators. KSMS offers a holistic solution for detecting, locating, and mitigating interference issues while delivering a full spectrum optimization stack, encompassing RF and over-the-air analog and digital demodulation. The software seamlessly integrates with Keysight FieldFox RF and MW analyzers, boasting an impressive operational frequency range spanning from DC to 54GHz. FieldFox analyzers can be easily configured for networked or mobile deployment, even within vehicles. With KSMS, users can swiftly establish ad-hoc or mobile signal monitoring networks to oversee RF spectrum activities, generate comprehensive reports on frequency allocation and usage, identify instances of interference, and pinpoint their origins through advanced techniques like Time of Difference of Arrival (TDoA) and Received Signal Strength (RSS) analysis. When equipped with a handheld directional antenna, FieldFox RTSA is a powerful tool for tracing the source of interference, especially in last-mile scenarios. This white paper serves as a comprehensive guide to understanding the capabilities and applications of KSMS, making it an invaluable resource for those seeking to modernize their spectrum management practices.
