The Keysight E8257DV02 is a millimeter-wave frequency extension module that extends PSG (Pathé Signal Generator) capabilities into the WR2.2 waveguide band. Manufactured by Virginia Diodes, Inc. and supplied by Keysight, this module transforms base signal generators into high-power millimeter-wave sources while preserving the frequency accuracy and resolution of the parent instrument. The E8257DV02 operates as part of an amplifier/multiplier chain, enabling direct frequency control and display from the connected signal generator. Pulse, FM, and phase modulation are available through the extension module, making it suitable for demanding millimeter-wave applications requiring signal fidelity and dynamic control.

– Compatibility & Integration
The E8257DV02 pairs directly with Keysight E8257D and E8267D PSG series. Compatible drive sources include E8257D, E8267D, N5183B MXG, and N5173B EXG. Also operates with legacy E8247C, E8257C, and E8267C synthesized sources. RF input power limits must be observed to prevent circuit damage.
