New Maury Microwave uCal™ Universal VNA Calibration Modules
uCal
Maury Microwave uCal (Universal VNA Calibration Modules) simplify and expedite the calibration process of a Vector Network Analyzer (VNA) by automating the use of calibration standards, reducing human error, and providing accurate results without manual intervention. A uCal contains a set of precisely defined and integrated calibration standards, each standard individually characterized with measurement uncertainty and stored on the uCal’s onboard memory. The uCal is equipped with electronic switches to select and connect the appropriate calibration standard to the VNA, thereby enabling rapid transitions between standards without physically disconnecting or reconnecting cables, reducing the chances of human-induced errors like improper torque or connector wear.
Eliminate Systematic Errors:
■ Directivity: Corrects for imperfections in the directional coupler.
■ Source Match: Compensates for mismatch at the VNA source port.
■ Load Match: Corrects for mismatch at the measurement port.
■ Reflection Tracking: Adjusts for errors in reflected signal measurements.
■ Transmission Tracking: Compensates for errors in signal transmission paths.
Calibration ensures that these systematic errors are accounted for and removed, improving measurement accuracy
Advantages include
■ Speed: Calibration is faster since there is no need to manually connect and disconnect standards.
■ Accuracy: Eliminates errors caused by manual handling, such as connector inconsistencies and improper torquing.
■ Ease of Use: Minimal user interaction is required, making calibration simpler and more accessible.
■ Reliability: Reduces wear and tear on VNA ports and connectors, prolonging their lifespan.
■ Consistency: Provides repeatable results across multiple calibration sessions and users.
■ Compatibility: Compatible with most well known VNA systems, including Keysight, R&S, Anritsu and others.
