Sweep Delay; Interval; Number Of Samples; Hold Time - Smu - Tektronix Keithley 4200A-SCS User Manual

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.
Refer to Operation mode timing diagrams

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
Delay Factor
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.

(on page 3-29). You can specify a Sweep Delay value from 0 s to 999 s. The default
