This unit
The Keysight E8257DS08 is a millimeter-wave source module that extends compatible PSG analog signal generators into the mmWave spectrum. Operating from 90 to 140 GHz, this OML AG series module connects directly to an E8257D or E8267D PSG equipped with Option 1EU, inheriting the host generator's frequency accuracy and resolution while delivering -2 dBm output power at 140 GHz. The module accepts RF input via SMA female connector and provides WR-08 waveguide flange output.
It supports FM, PM, and pulse modulation through the driving PSG. Power and control interface via rear panel connection; the host PSG supplies all DC requirements (+8 Vdc at 1.2 A max, +15 Vdc at 150 mA max). Compact form factor: 4.3 in × 2.8 in × 5.7 in (excluding waveguide length), weighing less than 2.0 lb.
Specified for indoor operation between +20 to +30 °C. Note: This product is obsolete.

Agilent / Keysight E8257DS08 — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight E8257DS08. 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 Agilent / Keysight E8257DS08 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.

Agilent / Keysight E8257DS08 calibration cost
NIST-traceable calibration for the Agilent / Keysight E8257DS08 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 →
