The Tektronix RSA5103A is a 3 GHz real-time spectrum analyzer combining traditional spectrum analysis, wideband vector signal analysis, and advanced triggering capabilities in a single platform. Designed for RF system design, testing, and troubleshooting, it delivers simultaneous real-time acquisition and analysis across a 1 Hz to 3.0 GHz frequency range with selectable real-time bandwidths from 25 MHz up to 165 MHz.
