SMC (Sensor Model Calibration) Release

SMC (Sensor Model Calibration) Release: Update April 28th, 2016

The novel SMC Sensor Model Calibration is a breakthrough in signal independent calibration of electromagnetic probes  linearized over a large dynamic range.

This new technique increases the flexibility of the end-user and reduces calibration costs while maintaining a low measurement uncertainty. Together with the upcoming MAIA Modulation and Audio Interference Analyzer, it enables the use of real-time information to optimize and automate linearization on-site. The method is described in detail in Novel Sensor Model Calibration Method for Resistively Loaded Diode Detectors, IEEE Transactions on Electromagnetic Compatibility, Volume: 57, Issue: 6, Dec. 2015. The linearization parameters for any communication system are derived from the calibrated model by numerical methods only, i.e., linearization for additional modulated signals can be provided without further measurements at the calibration laboratory. The result of the SMC calibration is equivalent to the direct PMR calibration of any UID. The differences between SMC calibration and direct calibration are evaluated on a routine basis to ensure the correctness of the provided uncertainty budget.

Calibration Procedure:
In this method, the sensor equivalent circuit is calibrated using the dynamic response to a set of generic signals.  

This calibration is a key feature of cDASY6 and also available as from now for DASY52 as it generates the PMR equivalent parameters of all available UIDs. Additional UID can be added later without returning the probe.  

SMC has been evaluated by the Swiss Accreditation Service and approved as part of our ISO/IEC 17025 accreditation.
