The Agilent/Keysight E4407B is an ESA-E series spectrum analyzer engineered for RF and microwave signal analysis, testing, and troubleshooting across 9 kHz to 26.5 GHz. The instrument delivers lab-grade performance in portable form, combining amplitude accuracy of ±0.4 dB with a displayed average noise level of −167 dBm (with internal preamp, Option 1DS) and a maximum 3rd order dynamic range of 99 dB. It reaches measurement readiness in 5 minutes and supports up to 40 measurements per second for high-speed remote operations.
