Agilent/Keysight E8257DS02

The Agilent/Keysight E8257DS02 is a millimeter-wave source module that extends the frequency capabilities of Keysight PSG Series Synthesized Sources. Manufactured by Oleson Microwave Labs and supplied by Keysight, this compact module enables high-performance signal generation across millimeter-wave bands when connected to compatible PSG base units. The E8257DS02 is part of a modular series designed to deliver direct frequency control, integrated modulation, and precise RF output from the host instrument.

– Compatibility & Integration

The E8257DS02 operates as a slave module requiring a compatible PSG Series host unit. Frequency range and output power specifications are module-specific; consult the appropriate model designation (e.g., E8257DS15, E8257DS12) for exact performance parameters. The supplied Source Module Interface cord provides both DC power distribution and protective earthing. Cabinet installation requires unrestricted convection airflow.
