The RSA503A was built to bring real-time spectrum analysis to solving the problems of spectrum managers, interference hunters and network maintenance personnel who need to track down hard to find interferers, maintain RF networks and keep records of their efforts. The heart of the system is the USB-based RF spectrum analyzer that captures 40 MHz bandwidths with great fidelity in harsh environments. With 70 dB dynamic range and frequency coverage to 7.5 GHz, all signals of interest can be examined with high confidence in your measurement results. The USB form factor moves the weight of the instrument off of your hands, and replaces it with a lightweight Windows tablet or laptop. Holding a light PC instead of a heavy spectrum analyzer means you can move faster, for longer, and get your work done faster.

The optional tracking generator enables gain/loss measurements for quick tests of filters, duplexers and other network elements, and you can add cable and antenna measurements of VSWR, return loss, distance to fault and cable loss as needed.
