This unit
The Agilent/Keysight 8673A is a synthesized signal generator delivering precise RF and microwave signal generation from 2 GHz to 26 GHz. Built on indirect synthesis with YIG-tuned oscillator phase-locked to a 10 MHz quartz reference, It has frequency stability better than 5 × 10⁻⁷ per day and exceptionally flat output across the full operating range. The instrument supports amplitude, frequency, and pulse modulation simultaneously, with output power continuously variable from +1 dBm to −120 dBm and 0.1 dB resolution.
Technical Specifications
Frequency & Stability- Frequency range: 2 GHz to 26 GHz
- Frequency resolution: 1 kHz to 4 kHz depending on band
- Frequency stability: 80 dB, rise/fall times <35 ns, pulse widths to 100 ns, rates to 1 MHz via TTL drive
- Simultaneous AM, FM, and pulse modulation supported Phase Noise

Agilent / Keysight 8673A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight 8673A. 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 8673A 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 8673A calibration cost
NIST-traceable calibration for the Agilent / Keysight 8673A 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 →
