3-Tones Measurements
The 3-Tones measurement is a measurement technique used to capture the low frequencies / long-term memory effects lead by the polarization, the thermal phenomenas and / or the trapping of the device. In this context, the main application is to extract the behavioral model of the DUT. Such a measurement is not possible to interpret traight away as its main purpose it to be injected as a VISION U-HFLF model, alongside with a 1-Tone characterization.
Overview
Requirements
Available measurements are linked to the Schematic configuration
and the selected Calibrations. In order to get access to 3-Tone
measurement, the following configuration must be respected:
- Vector Network Analyzer needs to be enabled in the Schematic
- 1-Port Enhanced Calibration or Full 2-Ports & Absolute Power Calibration needs to be enabled
To run 3-Tones measurements, the bench must be correctly set and calibrated. Once
these steps are done, it's possible to initialize the system ( 
) and access
