This unit
The HP/Agilent 8443A is a dual-function test instrument combining a tracking generator and frequency counter in a single 3U chassis. The tracking generator produces CW signals from 100 kHz to 110 MHz with amplitude control from -120 dBm to +10 dBm, synchronizing output frequency to an external spectrum analyzer for swept-frequency device characterization. The integrated frequency counter measures signals across the same 100 kHz to 110 MHz range with selectable resolution down to 10 Hz, plus external signal measurement capability to 120 MHz. Five operational modes
Marker, Track Analyzer, Restore Signal, External, and Scan Hold - accommodate diverse RF and microwave testing workflows. Amplitude flatness of ±0.5 dB and absolute accuracy of ±0.3 dB at 0 dBm/30 MHz enable reliable component alignment in telecommunications, aerospace, and defense environments.

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