This unit
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.
Product Status This product has been designated obsolete by the manufacturer. No direct replacement has been identified.
Keysight / Agilent E8257DS12 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Keysight / Agilent E8257DS12. Calibration covers output frequency accuracy, output power level accuracy across the full frequency range, AM/FM/PM/pulse modulation accuracy, harmonic and spurious output levels, and phase noise floor verification. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Keysight / Agilent E8257DS12 faults: YIG oscillator failure (no output or loss of lock), step attenuator wear (output drops or steps at set attenuation), ALC loop failure (uncontrolled output power), I/Q modulator assembly failure. HP/Agilent 836xx series most common faults are YIG oscillator failure and step attenuator contact wear causing output steps or drops at specific attenuation settings. Keysight E4428C/E4438C units most commonly develop ALC loop failure and I/Q modulator assembly faults. YIG oscillator replacement and attenuator service are stocked repairs.

Keysight / Agilent E8257DS12 calibration cost
NIST-traceable calibration for the Keysight / Agilent E8257DS12 is $450 (standard — pass/fail certificate and calibration sticker) or $650 (full measured data at every test point, reference standards documented, traceability chain included). Calibration for this instrument covers output frequency accuracy, output power level accuracy across the full frequency range, AM/FM/PM/pulse modulation accuracy, harmonic and spurious output levels, and phase noise floor verification. Turnaround is 1 to 3 business days after receipt. See full calibration details →
