Autonomous RF Measurements: Hands-Free Recalibration and Drift Compensation Across Multiple Temperatures

The Autonomous RF measurement assistant combines programmable positioners, a precise digital microscopy system, and advanced pattern recognition algorithms to enable fully autonomous, hands-free calibrations and measurements of RF devices over multiple temperatures.

This system manages the entire test flow for thermal and ambient testing, including automated calibration, monitoring to prevent measurement drift, and adjustment of probe spacing to account for growth and different probing geometries.

This presentation demonstrates the use of this approach for MLTRL calibrations both off and on wafer, showcasing the interaction between WinCal, Python, and analytical methods to evaluate calibration repeatability. Additionally, We will discuss the probe placement for unattended long-duration RF measurements.
