Keysight B1505A User’s Guide, Edition 12 5-3Measurement ExamplesGate Charge MeasurementGate Charge MeasurementThis section introduces the Power MOSET gate charge measurement examples.The gate charge measurement is comprised of two measurements (high current andhigh voltage gate charge measurements) and one characteristics extraction using twomeasurement results. First, you need to decide the following three key conditions todrive DUT.• Off voltageLoad voltage that DUT blocks during off state of switching operation.• On currentOn current that flows through the DUT during on state of switching operation.• Range of gate voltageGate voltages to turn on DUT and turn off DUT during switching operation.This section consists of the following sub-sections.• “Preparing Measurement”• “System Configuration and Open/Short Calibration”• “Preparing Measurement Setups and Performing Measurements”Preparing MeasurementWARNING Set the instrument output off before connecting or disconnecting a connectionwire.Press the B1505A front panel Stop key to set the output off. And confirm thatthe B1505A front panel High Voltage indicator is not lit.Désactivez la sortie de l'appareil avant de brancher ou de débrancher un câblede connexion.Appuyez sur la touche Stop du panneau avant du B1505A pour désactiver lasortie. Et confirmez que l'indicateur de tension High du panneau avant duB1505A n'est pas allumé.
