The RSA3303B is a portable Real-time Spectrum Analyzer (RSA) meant for lab or production line use with a frequency range of DC to 3 GHz is capable of capturing continuous, intermittent, or random signals. With Digital phosphor spectrum processing (DPX) this RSA provides the user the ability to view time-varying RF signals with color-graded displays based on frequency. For offline spectral analysis, .iqt and .tiq waveform data files can be offloaded to RSAVu Real-Time Spectrum Analyzer Software running on a PC.

This RSA is capable of performing spectrum analysis of power, ACPR, C/N, OBW, EBW, and spurious signals. Analog modulation analysis is possible with AM, PM, FM, ASK, and FSK signals. Additionally, this RSA can perform digital modulation analysis from BPSK to 256QAM (with option 21 of the RSAVu software), time characteristics analysis including pulse measurements, constellation analysis, EVM analysis, AM/AM and AM/PM distortion analysis, RFID analysis, signal source analysis, and CCDF analysis.
