The SAM-B series modular spectrum analyzer is a multi-functional modular instrument integrating spectrum analysis, vector network analysis, cable and antenna test, modulation analysis, monitoring and reception, and other functions. Featuring multiple measurement capabilities, excellent performance, a compact size, and ultra-high cost-effectiveness, this product is an ideal choice for system integration applications. With comprehensive testing functions, the SAM-B Series Modular Spectrum Analyzer is highly suitable for scenarios requiring testing of various parameters. It not only facilitates users’ integrated testing but also reduces costs. Standard LAN or USB control interfaces can be selected as needed to directly obtain measurement results. By using the standard SCPI command set and SDK, integrated testing systems can be quickly built and upgraded.
