Vector Signal Generator

The E4438C ESG Vector Signal Generator has a wide range of features included for testing both analog and digital communications systems. Nearly all planned and existing air interface standards can be tested to determine how well they perform using flexible options. Delivering calibrated test signals at baseband, IF, and RF frequencies up to 6 GHz with the Keysight E4438C, offering a large RF modulation bandwidth, an integrated baseband generator with arbitrary waveform and real-time I/Q capabilities, and abundant waveform playback and storage memory. The Keysight E4438C can be set up to handle a wide range of experiments, from producing experimental signals to changing almost every component of a digital signal or signal operating environment. The E4438C is a great option for testing wireless communications systems now and in the future because of the generator's flexibility and architecture that supports upgrades in the future.Features：Expandable architectureBroad frequency coverageChoice of electronic or mechanical attenuatorSuperior level accuracyWideband FM and ΦMStep and list sweep, both frequency and powerBuilt-in function generatorLightweight, rack-mountable2-year calibration cycleBroadband analog I/Q inputsI/Q adjustment capabilities and internal calibration routineExcellent modulation accuracy and stabilityCoherent carrier output up to 4 GHz
