Modern spectrum analyzers offer advanced measurement capabilities that cater to the diverse needs of labs. Features such as real-time spectrum analysis, vector signal analysis, and wideband signal capture enable researchers to capture and analyze complex RF signals with detail and accuracy, supporting advanced research in areas such as cognitive radio, software-defined radio (SDR), and 5G communications. For instance, in February 2023, Anritsu Company launched its Field Master MS2070A handheld spectrum analyzer. Providing necessary features and performance up to 3 GHz, the MS2070A conducts reliable and accurate RF measurements in a variety of general-purpose fields, labs, and manufacturing environments.
With the increasing demand for field and on-site measurements in various applications, there is a growing trend towards compact and portable spectrum analyzers. Manufacturers are developing handheld and battery-operated spectrum analyzers with ruggedized designs, user-friendly interfaces, and wireless connectivity options for portable spectrum analysis in field environments such as RF site surveys, spectrum monitoring, and interference hunting. For instance, in July 2023, Keysight Technologies, Inc. expanded its FieldFox portfolio with the N9912C FieldFox Handheld Analyzer, a software-defined RF testing platform offering field engineers more than 20 Vector Network Analyzer (VNA), Cable and Antenna Tester (CAT), and Spectrum Analyzer (SA) options for upgrade and download.
