Hold Time
The starting voltages or currents of a sweep may be substantially larger than the voltage or current
increments of the sweep. Accordingly, the source settling time required to reach the starting voltages
or currents of a sweep may be substantially larger than the settling times required to increment the
sweep. To compensate, you can specify a Hold Time delay to be applied at the beginning of each
sweep. You can specify a Hold Time of 0 to 1000 s.
See Choose hold and sweep delay times for CVUs (on page 6-95) for information on determining
hold times.
SMU Power On Sequence
When you run a test, the SMUs for the given test power on in a specific sequence. You can adjust
this sequence.
To adjust the power-on sequence for the SMUs:
1. Select the test.
2. Select Configure.
3. In the right pane, select the Test Settings tab.
4. Select Advanced.
5. Under SMU Power On Sequence, use the Move Up and Move Down buttons to change the
sequence.
6. Select OK.
Disable outputs at completion - SMU
If "Disable Outputs at Completion" is cleared, the SMU outputs remain at their last
programmed levels when the test is completed. To prevent electrical shock that could
cause injury or death, never make or break connections to the 4200A-SCS while the output
is on.
When a test is complete, you can disable the outputs or leave them enabled.
If you enable the outputs, the SMU starts the next test from its state at the end of the previous test. If
the next test does not use the SMU, the SMU remains in that state.
To set the output action on completion:
1. Select the test.
2. Select Configure.
3. In the right pane, select the Test Settings tab.
4. Select Advanced.
5. Select or clear Disable Outputs at Completion.
Output Values
You can export the readings from a test to the Analyze sheet for the test or the Analyze sheet for
subsite cycling. You select the values to be exported in the Output Values dialog box. A test can have
up to 20 output values.
If you are using subsites, each time a subsite is cycled, the measurements for the enabled Output
Values are placed in the Analyze sheet for the subsite. For example, if the subsite is cycled five
times, there will be five measured readings (Output Values) for the test. For details, see Subsite
cycling (on page 6-181).
