connect test
The connect test controls the matrix card switches. It connects the 4200-SMUs to the capacitor.
The Configure settings are:
• The OpenAll parameter is selected. This opens all matrix switches at the beginning of the test
sequence.
• The SMU1 parameter is set for pin 1. This connects SMU1 to column 1 of the matrix card. As
shown in cap-iv-cv-matrix connections (on page 4-36
), column 1 is connected to terminal A of the
capacitor.
• The SMU2 parameter is set for pin 2. This connects SMU2 to column 2 of the matrix card.
Column 2 is connected to terminal B of the capacitor.
• All the other instrument parameters are set for 0 (not used).
iv-cap test
In this test, SMU1 sources a fixed DC bias voltage to charge the capacitor and measures leakage
current as a function of time.
Force, measure, and timing settings
The parameter settings for the two SMUs are:
• SMU1 is configured to bias 5 V and perform 60 current measurements (at 100 ms intervals).
• SMU2 is configured as a Common for the return signal path.
In the project tree, select iv-cap and then select Configure. From the Configure pane, parameters
are set from the Test Settings pane and the Terminal Settings pane.
Analyze sheet
The test data is displayed in the Analyze sheet:
• Time: Timestamp of the measurement.
• AI: Measured current.
connect-cv test
This test controls the matrix card switches. It is used to disconnect the SMUs and then connect the
4210-CVU to capacitor.
Configure settings are:
• The OpenAll parameter is selected. This opens all switches after the iv-cap test is finished.
• The CVH1 parameter is set for pin 1. This connects CVH1 to column 1 of the matrix card. Column
1 is connected to terminal A of the capacitor.
• The CVL1 parameter is set for pin 2. This connects CVL1 to column 2 of the matrix card. Column
2 is connected to terminal B of the capacitor.
• All the other instrument parameters are set for 0 (not used).
