Perform a C-V test on an nMOSFET

To perform a test

:

1. In the project tree, select 

cv-nmosfet

. This test is

located under the 

4terminal-n-fet 

device.

In the Configure pane, on the next page, is where you define 

the test. In the test shown, the device is connected to the 

CVH1 and CVL1 terminals on the 4215-CVU.
In the following graphic, note that the Gate is CVH1 and Bulk 

is CVL1.
