This unit
The HP/Agilent 8443B Tracking Generator is a dual-function instrument that generates swept RF signals synchronized with spectrum analyzer tuning while providing integrated frequency measurement capabilities. The unit delivers tracking generator output from 100 kHz to 110 MHz at 50 Ohms impedance, with amplitude control spanning -120 dBm to +10 dBm. Front-panel controls offer 10 dB and 1 dB stepped attenuation plus continuous vernier adjustment for precise level setting. Amplitude flatness remains within ±0.5 dB across the full frequency range, with absolute accuracy of ±0.3 dB at 0 dBm and 30 MHz.

HP / Agilent 8443B — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the HP / Agilent 8443B. 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 8443B 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.

HP / Agilent 8443B calibration cost
NIST-traceable calibration for the HP / Agilent 8443B 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 →
