Keysight B1505A User’s Guide, Edition 12 5-5Measurement ExamplesGate Charge MeasurementSystem Configuration and Open/Short CalibrationSelect adapter and measurement resources used for the measurement, and thenmeasure the Open and Short calibration data of the selected adapter as follows.1. Click the Configuration button in the EasyEXPERT main window.The Configuration window appears.2. Click the Gate Charge Adapter tab to display the Gate Charge Adapter tabscreen.3. Select the adapter to be used, and specify the measurement resources to be used.4. Click the Start Calibration... button to measure the calibration data.The Gate Charge Calibration dialog box appears.If you have measured and saved the calibration data of the measurement path,click the Select Calibration Data... button to select and load the storedcalibration data. Go to the step 7.5. Click the Start button.Follow the instruction displayed on the dialog to measure the open and shortcalibration data.6. After finishing the calibration, click the Save and Apply button to save and applythe calibration data.7. Click the Close button to close the dialog box.8. Click the Apply button to apply the present settings, and then click the Closebutton to close the Configuration window.Preparing Measurement Setups and PerformingMeasurementsYou can use some application tests to perform the gate charge measurement. Thefollowing sections describe how to select and use application tests according to theMOSFET gate charge measurement examples. You can know information for IGBTdevices by replacing the DUT terminal names. For example, Qg (High Id + HighVds+ JESD24-2) in the PowerMOSFET category corresponds to Qg (High Ic +High Vce+ JESD24-2) in the IGBT category.For details of the application tests, see the help message for each test definition.• “Packaged Device Testing Using Current Load Transistor on the N1259A-014or N1265A-014”
