Test definition
The test is defined from the test Definition tab shown in Figure 1-35. As shown in the Definition tab,
the device is connected to three SMUs and one Ground Unit (GNDU). In general, SMU3 is used as
a voltage step function to provide four different gate voltages (2V, 3V, 4V, and 5V). SMU2 is used
to perform a 51 point sweep of drain voltage (0V to 5V) at each gate voltage. A current
measurement is performed at each voltage sweep point.
To define a test:
1. The setup for SMUs and the GNDU can be changed. A settings window is displayed by
clicking the appropriate force measure bar as shown in Figure 1-35.
