Tektronix RSA306B

This used Tektronix RSA306B is a USB powered real time spectrum analyzer designed to bring lab grade RF measurement capability into a small, portable form factor. It connects directly to a laptop and uses Tektronix SignalVu-PC software to perform spectrum analysis, spectrogram display, and basic modulation analysis, making it a favorite among field engineers, hobbyists, and educational programs. Its real time bandwidth and streaming capability allow users to capture and analyze transient or intermittent RF events that a traditional swept analyzer might miss. The unit being sold here has been tested for proper USB enumeration and confirmed to sweep and display signals correctly when paired with the SignalVu-PC application. Being a solid state device with no built in display, it shows minimal wear and functions essentially the same as when new, provided the software license and drivers are installed correctly. This makes it an attractive option for buyers comfortable running instrumentation through a PC interface. For students, makers, or engineers who need occasional access to real spectrum analysis capability without investing in a full benchtop unit, this RSA306B offers genuine Tektronix performance in a portable and affordable package. It is well suited for RF troubleshooting, interference identification, and educational demonstrations.
