The Agilent/Keysight E4408B ESA-L is a 26.5 GHz spectrum analyzer engineered for signal analysis across R&D, manufacturing, and field service environments. Operating from 9 kHz to 26.5 GHz, this instrument delivers ±1.1 dB amplitude accuracy, 82 dB third-order dynamic range, and displayed average noise level of -116 dBm at 1 GHz. The analyzer captures fast measurement updates at ≥28 spectra per second with sweep times from 4 ms to 4000 s and achieves ±2 kHz frequency accuracy after a 5-minute warm-up.
