The Agilent/Keysight E8257DS06 is a millimeter-wave source module that extends the E8257D PSG analog signal generator into the WR-06 waveguide band. Manufactured by Oleson Microwave Labs and offered by Keysight Technologies, this module delivers high-power test signals across 110 GHz to 170 GHz with output power up to +10 dBm and ±2 dB flatness. The module integrates directly with E8247C, E8257C, E8257D, E8267C, or E8267D PSG Series synthesized sources and is sized as a 4U half-rack unit with 213 mm depth.
