The Keysight E8257DV08 is a millimeter-wave frequency extension module that expands the capabilities of select Keysight and Agilent signal generators into the 90–140 GHz band. Manufactured by VDI, Inc., this WR8.0 waveguide-based extender delivers +9 dBm typical output power while preserving the frequency accuracy and resolution of the host generator. It integrates directly with the E8257D PSG, E8267D PSG, N5183B MXG, and N5173B EXG, enabling pulse, FM, and phase modulation at millimeter-wave frequencies through unified host control and display.
