Agilent Technologies E4440a Spectrum Analyzer

Agilent Technologies E4440A PSA Spectrum Analyzer delivers bench-top RF and microwave spectrum analysis from 3 Hz up to 26.5 GHz, with optional external mixers that extend measurement capability to 325 GHz. As a member of the PSA Series, it supports a maximum analysis bandwidth of 80 MHz and offers a wide attenuator range up to 70 dB in 2 dB steps, supplied as a unit-only listing (no cables or accessories). Key performance figures include a DANL of -169 dBm at 1 GHz, phase noise of -118 dBc/Hz at 10 kHz offset and -147 dBc/Hz at 1 MHz offset, and overall amplitude accuracy of ±0.19 dB. The instrument provides a TOI of +19 dBm and a maximum third-order intercept dynamic range around 116 dB at 1 GHz, enabling precise linearity and distortion assessments across its span. Typical applications span RF/microwave device characterization, modulation analysis, spur and harmonic testing, and precompliance verification in both research labs and production environments, making it suitable for detailed signal analysis, calibration workflows, and troubleshooting across communications and radar-related projects.
