This unit
The Keysight E8257D PSG is a microwave signal generator delivering output power, metrology-grade level accuracy, and superior phase noise performance across frequencies up to 67 GHz. This fully-synthesized source supports pulse, FM, and ΦM modulation, making it suitable for demanding RF and microwave test environments requiring precision frequency and level control. Frequency extension capabilities expand the E8257D into the millimeter-wave and terahertz bands through Virginia Diodes, Inc. (VDI) SGX modules.
These amplifier/multiplier chain (AMC) extensions preserve the accuracy and resolution of the base unit while enabling test signal generation up to 1.1 THz.
Technical Specifications
- Frequency Range (Base Unit): Up to 67 GHz
- Frequency Range (With Extenders): Up to 1.1 THz
- Output Power: across frequency range; module-dependent output from +8 dBm to +20 dBm
- Level Accuracy: Metrology-grade
- Phase Noise: Superior performance specification
- Modulation: Pulse, FM, ΦM
- CW Frequency Switching: ≥5 ms to within 0.05% of final frequency
- Trigger Response: From GPIB trigger to frequency within 0.1 ppm (above 250 MHz) or 100 Hz (below 250 MHz)
Key Features
- Full frequency synthesis with fast CW switching capability
- Multiple frequency extension modules targeting 50 GHz to 170 GHz bands
- High output power across modulation types

Agilent / Keysight E8257DV1B — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight E8257DV1B. 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 E8257DV1B 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.
