IVCAD provides corrected data at the DUT reference plane. The correction terms are calculated during the calibration process using a step-by-step wizard. Depending on the setup configuration, different calibrations can be performed in IVCAD:
- Coaxial Calibration
- Waveguide Calibration
- Unsexed Calibration (for On-wafer measurements)
- Time Domain Calibration
In the case of a scalar setup, the calibration procedure is based on power measurements using power meters and signal generators. For vector setups, the Calibration of the Vector Network Analyzer (VNA) is necessary to extract the error terms. Furthermore, depending on the VNA configuration. To minimize the source of errors, IVCAD provides a state-of-the-art calibration wizard that relies on the schematic setup to identify the type of Calibration that is possible to perform and guides the end-user through all the steps, including the validation process to verify and assess the expected accuracy.
The auto tuner de-embedding wizard is a unique feature in the VRLP setup in IVCAD that allows the recalculation of the tuner calibration and its related error terms when the tuners’ terminations (Source or load) change after the setup calibration. This can happen if we need to change one of the setup components to accommodate the device (switch to higher power handling or wider frequency band components and change a damaged one). The auto de-embedding wizard saves a considerable amount f time and avoids re-calibrating the full system when only a passive device needs to be replaced.
