The Agilent/Keysight E4844A is a single-channel network analyzer delivering 660 MSa/s sampling capability. Though now obsolete, Keysight maintains full support including calibration and repair services, allowing continued operation or smooth transition to current instruments. This analyzer characterizes electronic components and systems across a broad measurement scope, from passive networks to active devices.
Technical Specifications
The E4844A measures S-parameters (magnitude and phase), return loss, gain, standing wave ratio, impedance, and nonlinear characteristics. Measurement integrity depends on proper calibration using Keysight’s advanced calibration techniques. The instrument supports trace math functions, marker searches, and time-domain analysis for comprehensive data interpretation. – Key Features • 660 MSa/s sampling rate
