Test Procedure - Standard DPT Test
Test Procedure - Standard DPT Test
1 Install the PD1000-60901 TO-247-3 DUT Test Module on the Test Fixture.
2 Insert the two SCT2080 FETs in the PD1000-60901 TO-247-3 Test Module.
3 Install the High-Side and Low-Side Gate Drive modules on the Test Fixture.
4 Perform a system calibration. See
5 Set the following test parameters in the PD1000A Control Software.
Keysight PD500A Double-Pulse Test System Installation Guide
Optionally, attach the heater/Thermocouple to the Low-Side device.
System Calibration". At a minimum, the following two steps should be
performed:
– Oscilloscope Probe Compensation
– Oscilloscope Probe Deskew
If this is the first time the PD1500A system is tested or used,
perform all system calibration steps. See "PD1500A Double-Pulse
Test System Calibration" on page 59. This ensures the Gate Drive
modules, Clamp Module, and all probes are functional and
calibrated.

Select the
tab.
– Select device type: FET
– Gate Parameters:
-- After installing the 10 Gate Drive Modules (do not install the Clamp
Circuit Module at this time) and prior to running the test, click the Gate
Parameters > Gate Resistance refresh icon. This reads the calibrated value
of the gate resistor on the Gate Drive Module. It should show value of
Gate Resistor (~10 ) for both Low-Side and High-Side Gate Drive
modules.
