Keysight (Agilent) 16074A

The Keysight (Agilent) 16074A is a calibration R-L standard fixture designed for calibration and performance testing of four-terminal-pair LCR meters. It delivers accurate impedance measurements across frequencies up to 13 MHz, making it essential for precision component evaluation and quality control in laboratory and industrial environments.

– Technical Specifications

The 16074A operates with a four-terminal-pair configuration optimized for high-accuracy measurements. It maintains performance to 13 MHz and includes eight resistance standards spanning from 0 Ω to 100 kΩ, plus two quasi-inductance standards and open/short terminations.

Resistance standards are segmented by application: the 0 Ω through 100 Ω standards employ thin-film resistors with minimal residual resistance and stray capacitance, while the 100 Ω through 10 kΩ standards are shielded to suppress noise coupling. Standards from 0 Ω to 100 Ω are optimized for phase measurement calibration with minimal residual reactance. Higher-value standards (1 kΩ, 10 kΩ, 100 kΩ) are calibrated for resistance measurement with ±0.1% accuracy.

Quasi-inductance standards (100 μH and 100 mH) are constructed using two resistors and one capacitor to synthesize equivalent inductance. Users must measure equivalent inductance values before operation to confirm LCR meter inductance measurement functionality.
