This unit
The Agilent/Keysight 8664A is a synthesized signal generator spanning 100 kHz to 3.0 GHz, engineered for RF and microwave applications demanding spectral purity and frequency stability. It delivers output levels from +13 dBm to −139.9 dBm with 0.01 Hz resolution, supporting AM, FM, phase modulation, and pulse modulation. The instrument combines low phase noise (−134 dBc/Hz at 1 GHz, 20 kHz offset), digitally stepped and phase-continuous frequency sweep, and dual independent modulation sources with selectable waveforms and rates to 400 kHz.
Technical Specifications

- SSB Phase Noise: −134 dBc/Hz at 1 GHz carrier, 20 kHz offset (standard)
- Non-harmonic Suppression: Typically below −100 dBc
- RF Leakage: < 16 µV typical; < 2 µV with Option 010 (resonant dipole); < 0.05 µV with Option 010 (two-turn loop)
- Power Requirements: ±10% of 100 V, 120 V, 220 V, or 240 V; 48–440 Hz; 500 VA
Key Features
- Modulation: AM, FM (rates to 2 MHz, deviations to 10–20 MHz), phase modulation, and pulse modulation (50–999 ns adjustable width/delay, rise/fall 80 dB with options)
- Frequency Sweep: Digitally stepped and phase-continuous modes; 40 MHz span at maximum carrier frequency
- Internal Modulation Sources: Two simultaneous, independently configurable sources with sine, triangle, sawtooth, square, and Gaussian noise waveforms; rates from 0.1 Hz to 400 kHz (sine/noise) or 50 kHz (other waveforms)
- Optional Enhancements: Low-noise option (Option 004), high-stability timebase (Option 001), internal 2 GHz frequency counter (Option 011), reduced leakage configuration (Option 010), pulse modulation capability (Option 008)

Agilent / Keysight 8664A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight 8664A. 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 8664A 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 8664A calibration cost
NIST-traceable calibration for the Agilent / Keysight 8664A 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 →
