This unit
The Agilent/Keysight 8621B is a synthesized sweep signal generator delivering precise RF and microwave signal generation from 45 MHz to 20 GHz with 1 Hz frequency resolution. Purpose-built for integration with Agilent 8510 systems, this instrument combines the accuracy of a synthesized source with sweep oscillator speed, making it suited for legacy test configurations and specialized measurement requirements.
Technical Specifications
Frequency Coverage: 45 MHz to 20 GHz with 1 Hz resolution. Output Power: Maximum calibrated output reaches +13 dBm across the full range. Minimum settable output is –20 dBm (standard) or –110 dBm with Option 001. Power resolution is 0.02 dB. Spectral Purity: Harmonics suppress to < –50 dBc below 26.5 GHz. Subharmonics remain below –50 dBc between 7 GHz and 20 GHz. Nonharmonically related spurious signals achieve < –60 dBc from 10 MHz to 20 GHz. Output Impedance: 50 ohms nominal, terminated with a precision 3.5-mm male connector on the front panel. Physical Dimensions: 178 mm H × 425 mm W × 648 mm D; 27 kg weight. Environmental Ratings: Operating temperature 0 °C to +45 °C; storage range –40 °C to +70 °C. Humidity tolerance < 95% RH from 0 °C to 45 °C. Maximum operation altitude 2000 m.Key Features
- No front panel keyboard or display - remote control via rear panel connections
- 1 Hz frequency resolution for precise spectral placement
- Rear panel output option available
- Extended dynamic range to –110 dBm with power option
- Designed for pollution degree 2 environments
Typical Applications Legacy network analyzer systems; component characterization requiring clean spectral output; frequency sweep testing in RF and microwave bands.
Compatibility & Integration Optimized for Agilent 8510 measurement systems. Requires external control interface due to absence of local front panel controls.
Agilent / Keysight 8621B — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight 8621B. 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 8621B 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 8621B calibration cost
NIST-traceable calibration for the Agilent / Keysight 8621B 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 →
