This unit
The Agilent/Keysight 8654A is a compact RF signal generator delivering stable, accurate signals from 10 Hz to 520 MHz. Engineered for receiver testing, system calibration, and general-purpose signal generation, it combines broad frequency coverage with excellent output control and signal purity in a single instrument.
Technical Specifications
Frequency Range: 10 Hz to 520 MHz across six contiguous bands: 10–18.6 MHz, 18.6–35 MHz, 35–66 MHz, 66–130 MHz, 130–250 MHz, and 250–520 MHz. Output Level: +10 dBm to −130 dBm into 50 Ω load. Option 003 reduces maximum output to +8 dBm. Output resolution is 0.1 dB, with absolute accuracy of ±1 dB above −127 dBm and typically ±3 dB below that threshold. Output Impedance: 50 Ω, AC coupled. Signal Purity: Harmonic distortion below +3 dBm is <−20 dBc (or <−15 dBc with Option 003). Subharmonic and non-harmonic spurious signals measure <−100 dBc. Residual AM averages <−55 dBc in a 50 Hz to 15 kHz post-detection bandwidth. Residual FM on CW is <0.3 ppm (0.3–3 kHz bandwidth) or <0.5 ppm (50 Hz–15 kHz bandwidth). SWR: <1.7:1 below −2 dBm output; <1.3 on 0.1 V range or lower (0.1% deviation- 8654B variant provides calibrated, metered FM across four deviation ranges: 0–3 kHz, 0–10 kHz, 0–30 kHz, and 0–100 kHz
- External modulation bandwidth >25 kHz when driven from 600 Ω or lower impedance source
Typical Applications
- Receiver sensitivity and linearity measurements
- RF and intermediate-frequency system calibration
- General laboratory signal generation
- Modulation index testing and AM/FM performance validation
Compatibility & Integration Standard 50 Ω output connector. AC-coupled design. Accepts both internal and external modulation signals via dedicated 600 Ω input.

Agilent / Keysight 8654A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight 8654A. 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 8654A 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 8654A calibration cost
NIST-traceable calibration for the Agilent / Keysight 8654A 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 →
