Executing Self-Test and Leak Test
Using the Self-Test Utility
To Execute Leak Test
NOTE Leak Test is for checking leakage current of the E5250A with plug-in cards
installed. If leak test result is too large for your application, contact nearest Agilent
Technologies Service Center. Leak test does not verify specifications of the E5250A
and installed cards.
The Leak Test applies 10 Vdc to the specified input port of the E5250A, and
measures the leakage current. The test limits are shown in Table 3-4.
You specify an input port of the E5250A, and specify the 4155/4156 SMU to use.
The Leak Test automatically connects the specified input port to each output port
consecutively, and uses the 4155/4156 SMU to measure the leakage current for each
channel.
You need to execute this test for each input port.
