Rigol RSA3045-TG Real-Time Spectrum Analyser

The RSA3045-TG is a 9kHz to 4.5GHz Real-Time Spectrum Analyser. The Rigol RSA3000 series real-time spectrum analysers combines the power of a high-performance conventional spectrum analyser with superior real-time performance. Available in 3.0GHz and 4.5GHz models, all RSA3000 series analysers provide a resolution bandwidth (RBW) down to 1Hz (optional), a noise floor as low as -161dBm/Hz (typ.) and phase noise of -102dBc/Hz @ 10kHz offset (typ., f = 1GHz). In addition, the analyser features up to 40MHz of real-time bandwidth (optional), a minimum probability of intercept (POI) of 7.45µs, 7-rich visualisation modes and powerful triggering capability. The Rigol RSA3000 series is a complete analysis package for engineers developing and integrating todays wireless technologies utilising complex and dynamic modulation schemes.
