Agilent/Keysight E4445A

The Agilent/Keysight E4445A is a high-performance PSA spectrum analyzer engineered for RF and microwave measurements across 3 Hz to 13.2 GHz. It delivers exceptional sensitivity with displayed average noise level of -169 dBm @ 1 GHz, absolute amplitude accuracy of ±0.19 dB, and phase noise of -118 dBc/Hz @ 1 GHz (10 kHz offset). The instrument features an all-digital IF section with configurable analysis bandwidth options—standard 10 MHz, optional 40 MHz or 80 MHz, extending to 300 MHz for calibrated VSA measurements.
