The Keysight (formerly Agilent / HP) E4407B is a 26.5 GHz mid-performance spectrum analyzer belonging to the ESA-E Series. Designed for general-purpose RF and microwave measurements in both laboratory and field environments, it offers a standard frequency range of 9 kHz to 26.5 GHz (extendable down to 100 Hz with optional configuration). Key features include an overall amplitude accuracy of ±0.4 dB, a 10 MHz analysis bandwidth, and a highly sensitive displayed average noise level (DANL) of -167 dBm when utilizing the internal preamplifier.
