Originální abstrakt

This work experimentally evaluates the measurement accuracy of picofarad-range capacitors using the Agilent 4294A impedance analyzer. The influence of measurement bandwidth, excitation voltage, connection method (fixtures vs. probe), and averaging techniques was systematically investigated. Results show that while magnitude measurements remain stable, phase accuracy strongly depends on bandwidth and excitation level. Standard fixtures (16047E, 16034G) significantly outperform the 42941A probe, and moving averaging further improves phase stability. Overall, impedance values of capacitors in the tens-of-picofarads range can be measured with higher accuracy than predicted by datasheet error formulas, enabling reliable element characterization.
