Agilent / Keysight E1441A Arbitrary Waveform Generator

The Agilent/Keysight E1441A is a C-size VXI arbitrary waveform generator employing direct digital synthesis to produce standard and custom waveforms for electronic testing, simulation, and communication system development. This message-based module delivers isolated output design that minimizes ground loops and common-mode noise, enhancing signal integrity across complex measurement scenarios. The E1441A provides substantial waveform generation capability at lower cost than comparable standalone function generators. Note: This product is obsolete due to non-compliance with EU RoHS directive 2011/65/EU; Keysight continues service and support through its published end-of-life date.
