The Keysight/Agilent/HP 04294-61001 is a 100 Ohm precision resistor module designed as a load element for 4-terminal pair extension within the Agilent 4294A Precision Impedance Analyzer system. This accessory delivers stable, accurate resistance values essential for impedance characterization, calibration, and material property analysis across the analyzer’s full operating range.
## Technical Specifications
• **Resistance Value:** 100 Ω
• **Module Type:** Load resistor for 4-terminal pair extension
• **Primary Application:** Agilent/Keysight 4294A Precision Impedance Analyzer
## Key Features
The 04294-61001 integrates with the 4294A analyzer, which operates from 40 Hz to 110 MHz with basic impedance accuracy of ±0.08%. The analyzer supports test signal levels from 5 mV to 1 Vrms or 200 µA to 20 mArms, with DC bias capability from 0 V to ±40 V or 0 mA to ±100 mA. This configuration enables precision measurements of low-loss components with excellent High Q/Low D accuracy.
The resistor module supports the 4294A’s advanced calibration and error compensation functions, which minimize measurement uncertainty for in-fixture devices. Built-in analysis tools include marker functions for resonant frequency and impedance identification, equivalent circuit modeling, and IBASIC programming for automated measurements and remote control. Non-volatile memory (10 Mbyte) permits saving and recalling measurement data and system configurations.
## Typical Applications
• Impedance analyzer calibration and validation
• Precision resistance reference for component and circuit characterization
• Material property measurements via dielectric and magnetic test fixtures (16451B, 16454A)
• Design, qualification, and production testing workflows
• In-fixture impedance measurement with error correction
## Compatibility & Integration
This resistor module is a furnished accessory for the Agilent 4294A Precision Impedance Analyzer. It interfaces through the analyzer’s terminal system and functions as an integral load element within the 4-terminal pair measurement architecture.
