The Tektronix RSA306B is a USB-powered real-time spectrum analyzer delivering signal acquisition and analysis from 9 kHz to 6.2 GHz. Its architecture separates hardware signal capture from PC-based processing, enabling portable field testing, laboratory measurements, and educational analysis without sacrificing performance. The 40 MHz acquisition bandwidth captures transient events with 100 µs minimum signal duration at 100% probability of intercept, extensible to 15 µs on high-performance systems. Fast 2-per-second sweeps across the full 6.2 GHz span rapidly identify unknown signals.
