Section 3: Setting up SMUs in Clarius

When Sampling Mode is selected, all device terminals are set to a static operation mode, such as
Open or Voltage Bias.
Operation mode timing diagrams
(on page 5-22) for additional detail.
Sweep Delay
If you are using a sweep operation mode and need extra settling time before each measurement, you
can specify an additional delay with the Sweep Delay setting. Sweep Delay is independent of the
(on page 3-29). You can specify a Sweep Delay value from 0 s to 999 s. The default
Sweep Delay value is 0 s.
Interval
Sampling mode only. The time between measurements (points). The interval can be set from 0 s to
1000 s.
Number of Samples
Specifies the number of points to be acquired. Set the number of samples to a value from 1 to 4096.
Hold Time - SMU
The starting voltages or currents of a sweep may be substantially larger than the voltage or current
increments of the sweep. This mean that 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, which applies a delay at the
beginning of each sweep. You can specify a Hold Time of 0 s to 1000 s.
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
.
