IQSTAR 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. The Vector Network Analyzer (VNA) calibration is necessary for vector setups to extract the error terms.
Furthermore, the vector calibration and power calibration can differ depending on the VNA configuration, which can be set to use three (3) or four (4) receivers. Therefore, and to minimize the source of errors, IQSTAR provides a state-of-the-art calibration wizard that relies on the schematic setup to identify the type of calibration possible to perform and guides the end-user through all the steps, including the validation process verifying and assessing the expected accuracy.
