This unit
The Agilent/Keysight 41941A is an impedance probe kit that extends the measurement capabilities of the 4194A Impedance/Gain-Phase Analyzer. It enables in-circuit impedance characterization of components, printed circuit patterns, and circuit input/output impedance across a broad frequency range. The kit supports DC biased measurements for evaluating DC parameters in inductors, capacitors, semiconductors, and materials, making it essential for component and circuit characterization in development and production environments.
Technical Specifications
Frequency Range: 10 kHz to 100 MHz (when used with 4194A) Impedance Measurement Range: 0.1 Ω to 1 MΩ Measurement Accuracy: 1.5% to 3%; calibration accuracy guaranteed to probe tips DC Bias Capabilities:- External DC Bias: ±150 Vdc, ±0.5 A
- Internal DC Bias (4194A): ±40 V for swept bias measurements
- Maximum combined AC + DC voltage: ±40 V peak
- DUT power consumption limit: 25 W maximum with external bias Test Cable Length: 1.5 m (3-meter version 41941B available)
Key Features
- Probe tip calibration standards included with automatic calibration function to eliminate residual impedance and stray admittance errors
- Multiple probe adapters: 3.5-mm short, 3.5-mm 50 Ω load, pin probe for in-situ measurements, ground lead, and BNC adapter
- Calibration accuracy guaranteed to probe tips for reliable in-circuit measurements
Typical Applications
- Component-level impedance measurements on PCBs
- DC parameter characterization of reactive components under bias
- Input/output impedance evaluation of active circuits
- Material and semiconductor impedance assessment

Agilent / Keysight 41941A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight 41941A. 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 41941A 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.
