This unit
The HP/Agilent 83555A is a millimeter-wave source module that generates RF signals across the 33 GHz to 50 GHz band. Driven by compatible Keysight microwave sources, it extends baseband synthesizers into the millimeter-wave spectrum for waveguide-based testing. The module delivers leveled output power with tight accuracy and low spurious content, supporting external pulse, AM, and FM modulation for dynamic signal characterization.

Leveled output power for stable signal generation
Low harmonic and non-harmonic spurious content
Compact waveguide-flange output (WR-28)
Frequency multiplication architecture - extends driving source capabilities into Ka-band
Typical Applications
Wireless communication system testing
Radar system characterization
Millimeter-wave component evaluation
Waveguide-based signal generation
Compatibility & Integration The 83555A integrates with HP 8350B series sweep oscillators and the HP 8350A RF plug-in for swept-frequency measurements. System frequency coverage scales directly with the driving microwave source; sources operating 11 GHz to 20 GHz with output power exceeding +17 dBm enable coverage to 110 GHz across waveguide bands when paired with modules like the HP 83623B, 83624B, or HP 8349B amplifier. Compatible with HP 8510 vector network analyzers, HP 8757A scalar network analyzers, HP 5343A frequency counters, and HP 8970 noise figure meters.

HP / Agilent 83555A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the HP / Agilent 83555A. 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 HP / Agilent 83555A 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.
