Introduction of Tektronix RSA503A
The Tektronix RSA503A is a portable USB real-time spectrum analyzer designed to provide high-performance RF signal analysis in a compact and rugged form factor. Ideal for both field and lab use, the RSA503A combines powerful capabilities with the flexibility of USB connectivity, allowing it to be paired with a laptop or tablet for enhanced portability and ease of use.
The RSA500 series is designed to deliver real-time spectrum analysis for spectrum managers, interference hunters, and network maintenance personnel who need to locate elusive interferers, maintain RF networks, and document their activities. At the core of the system is a USB-based RF spectrum analyzer that accurately captures 40 MHz real-time bandwidths, even in challenging environments.
