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 E5250 A
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.
