Agilent / Keysight E4443A 6.7GHz PSA Spectrum Analyzer

The Agilent/Keysight E4443A is a PSA spectrum analyzer delivering precision signal analysis from 3 Hz to 6.7 GHz. Built for aerospace, defense, and wireless communications applications, this instrument combines exceptional sensitivity with flexible measurement architecture. The DANL reaches -170 dBm typical with the optional low noise path, while phase noise performance stands at -107 dBc/Hz at 10 kHz offset (1 GHz carrier).

Resolution bandwidth spans 1 Hz to 8 MHz in 1-3-10 sequence with ±5% typical accuracy. The analyzer supports up to 30 MHz real-time analysis bandwidth and captures I/Q data for offline processing. Dynamic range of 75 dB (10 Hz RBW) and third-order intercept of +17 dBm typical ensure clean measurements in dense RF environments.
