Model 4284A Or 4980A Test Example; C-V Sweep - Keithley 4200A-SCS Reference Manual

Appendix C: Using a Keysight 4284/4980A LCR Meter

Model 4284A or 4980A test example

The following test example for the Model 4284A or 4980A LCR Meter is controlled by the
ivcvswitch project with an added user test module (UTM) created from a user module from the
HP4284ulib user library. A switch matrix is not used for this example.

C-V sweep

This example assumes that the Model 4284A or 4980A is already connected directly to the device
under test (DUT). The DUT can be a device installed in a test fixture or a MOS capacitor on a wafer.
Complete the following steps to do a C-V sweep.
Set up the project:
1. From the Project Library, select the ivcvswitch project.
2. Select Create.
3. At the bottom of the project tree, add another capacitor from the Device Library.
4. From the Test Library, select Custom Test, Choose a test from the pre-programmed library
(UTM).
5. Drag Custom Test to the project tree under the capacitor. The test has a red triangle next to it to
indicate that it is not configured.
6. Select Rename.
7. Enter hpcvsweep and press Enter.
8. Select Configure.
9. In the Test Settings pane, select the user library HP4284ulib.
10. Select the user module CvSweep4284.
11. On the Configure pane, you can modify the test parameters as needed. With the settings shown
in the figure below, the Model 4284A or 4980A does a +3 V to −4 V staircase sweep using 50 mV
steps. A measurement is made on each step of the sweep. For details on the test description, see
CvSweep4284 User Module
12. Select Run to execute the test.
