Product Overview

Key Features and Functions
RF performance and leading-edge baseband generation
The E4438C ESG vector signal generator combines outstanding RF performance and sophisticated baseband generation to deliver calibrated test signals at baseband, IF, and RF frequencies up to 6 GHz. Offering an internal baseband generator with arbitrary waveform and real-time I/Q capabilities, ample waveform playback and storage memory, and a wide RF modulation bandwidth, the E4438C ESG is equipped to test today’s complex wireless systems and their components.
