This unit
The Agilent/Keysight 4084A is a precision impedance analyzer engineered for accurate characterization of electronic components, materials, and circuits across frequencies from 40 Hz to 110 MHz. Operating in a four-terminal pair configuration, it delivers comprehensive measurement capabilities across 20 distinct parameter formats, making it essential for component validation, materials research, and production quality assurance.
Technical Specifications
Measurement ParametersThe 4084A quantifies impedance in multiple representations: |Z|-θ and |Y|-θ (magnitude and phase), R-X (resistance and reactance), series and parallel inductance configurations (Ls-Rs, Ls-Q, Lp-G, Lp-Q, Lp-Rp), series and parallel capacitance configurations (Cs-Rs, Cs-Q, Cs-D, Cp-G, Cp-Q, Cp-D, Cp-Rp), G-B (conductance and susceptance), and complex Z-Y. Derived parameters include |Z|-Ls, |Z|-Cs, |Z|-Lp, |Z|-Cp, |Z|-Rs, |Z|-Q, and |Z|-D. Frequency & Resolution
Frequency range spans 40 Hz to 110 MHz with 1 mHz resolution. Signal Source
Voltage test signal: 5 mVrms to 1 Vrms (1 mV resolution). Current test signal: 200 µArms to 20 mArms (20 µA resolution). Test signal level sweeping evaluates voltage and current dependency. DC Bias
DC voltage bias: 0 V to ±40 V (1 mV resolution). DC current bias: 0 mA to ±100 mA (40 µA resolution). Auto Level Control (ALC) feedback maintains precise bias throughout sweeps, enabling C-V characterization. Bias sweeping supports dependency evaluation across the full range.
Key Features
- Four-terminal pair configuration with BNC female connectors for high-accuracy measurements
- Signal level dependency evaluation via voltage and current sweeps
- DC bias dependency analysis with automatic level control feedback
- Single-port measurement capability via optional 42942A Terminal Adapter (7 mm) or 42941A Impedance Probe (3.5 mm)
Typical Applications
- Component characterization in R&D environments
- Varactor diode C-V characterization with DC bias sweep capability
- Manufacturing quality control and production testing
- Material impedance profiling across wide frequency span
Compatibility & Integration The standard four-terminal pair port accepts BNC female connectors. Optional adapters convert to single-port terminal configurations for alternative measurement geometries.
Agilent / Keysight 4084A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight 4084A. Calibration covers calibration scope varies by instrument type: vacuum gauges are verified at multiple pressure points against NIST-traceable pressure standards; spectrophotometers at wavelength accuracy and photometric accuracy points; strain gauge indicators at bridge excitation accuracy and full-scale output accuracy; pH meters against certified buffer solutions at pH 4, 7, and 10.. All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Agilent / Keysight 4084A faults: vacuum gauge filament failure (ionization gauges), spectrophotometer D2 lamp end-of-life, wavelength motor failure, strain indicator front-panel binding post corrosion, pH electrode conditioning failure. Most specialty laboratory instruments fail at their electromechanical interfaces first — vacuum gauge connectors and filament assemblies, spectrophotometer lamp housings and motor drives, strain indicator binding post corrosion. Component-level repair is standard; manufacturer support for legacy instruments is often limited, making third-party bench repair the practical path.
