The Agilent/Keysight E4407B ESA-E Spectrum Analyzer delivers signal analysis from 9 kHz to 26.5 GHz with internal mixing, extending to 110 GHz and 325 GHz using external mixers. Built for R&D, manufacturing, and field testing, this portable analyzer provides ±1 dB amplitude accuracy to 3 GHz and ±2.5 dB to 26.5 GHz, with DANL reaching -167 dBm using the internal preamp. The instrument achieves 99 dB third-order dynamic range and delivers up to 40 measurements per second with 1 ms RF sweep time. Resolution bandwidth spans 1 kHz standard (10 Hz optional), with variable sweep points from 101 to 8192. The 50 Ω type N input accepts continuous power to +30 dBm and peak pulse power to +50 dBm. Frequency reference stability is ±5×10–6 across temperature. Operation via 195–250 Vrms AC or 12–20 Vdc, consuming <300 W AC or <200 W DC. Five-minute warm-up ensures guaranteed measurement accuracy.
