The Keysight E8257DS12 is a millimeter-wave source module that extends signal generator capabilities into the 60 GHz to 90 GHz band. This plug-in module interfaces directly with Keysight E8257D or E8267D (Option 1EU) signal generators, inheriting the host PSG’s frequency accuracy and resolution while delivering high-power millimeter-wave test signals. Output connects via WR-12 waveguide flange.
Technical Specifications
• Frequency Range: 60 GHz to 90 GHz
• Maximum Output Power: +6 dBm @ 90 GHz
• Output Port: WR-12 waveguide flange
• Modulation Modes: FM, PM, and Pulse
• Input Protection: Integrated power protection
– Key Features
• Direct frequency control and display through host PSG interface
• Leverages host generator’s frequency accuracy and control resolution
• DC power supplied via PSG source module interface
• Optional EA2 electronic attenuator: up to 40 dB attenuation range
– Compatibility & Integration
The E8257DS12 requires a compatible host signal generator for operation:
• Keysight E8257D Signal Generator
• Keysight E8267D Signal Generator (Option 1EU required)
The module operates as a driven extension of the host PSG, deriving all frequency control, modulation capability, and timing references from the parent instrument. No standalone operation is supported.
