The Keysight (formerly Agilent/HP) E4403B-BAS is a reliable, general-purpose basic spectrum analyzer from the ESA-L series, designed for bench-top, manufacturing, and service environments. It offers a frequency range of 9 kHz to 3.0 GHz, delivering rapid measurements and high accuracy. The 'BAS' configuration provides excellent core value with features like PowerSuite one-button measurements, a 5-minute warm-up time, and backwards compatibility with 8590 series code.
