The Tektronix RSA513A is a USB 3.0 real-time spectrum analyzer engineered for signal analysis, spectrum monitoring, and interference detection from 9 kHz to 13.6 GHz. With 40 MHz acquisition and real-time bandwidth, it captures transient signals and performs vector analysis at acquisition rates up to 10,000 spectrograms per second. The instrument delivers 70 GHz/sec full-span sweep capability and spurious-free dynamic range of 70 dBc (typical). Its compact design enables deployment in field and laboratory settings, operating through Tektronix SignalVu-PC software on a user-supplied PC.
