Section 6: Keithley Interactive Test Environment (KITE)
The timing elements in
• If needed, you can use a Hold Time (HT) to allow for extra source settling after initial
application of voltages/currents by the SMUs. Hold Time is a global setting and is therefore
the same for all SMUs in the test system.
• A range-dependent delay (D) is automatically applied by an SMU before each
measurement to allow for source settling (refer to
system are synchronized. Therefore, the delay time applied by the most-delayed SMU is the
delay time applied by all SMUs.
NOTE
• The Measure Time (MT) is determined by the Filter Factor and the A/D Integration Time.
All SMUs in the test system are synchronized. Therefore, the Measure Time (MT) for the
SMU requiring the longest measure time is the same for all SMUs in the test system.
Understanding and configuring the Timestamp Enabled checkbox
• When the Timestamp Enabled checkbox is checked, KITE records the elapsed time for
each measurement. Each elapsed time value is placed in the Sheet tab Data worksheet in
the same row as the measurement.
• Each elapsed time is measured relative to the beginning of the test, when voltage or current
is first applied to the device. If KITE requires only one reading for a measurement, then
KITE records the timestamp at the beginning of this reading. See

In sampling mode, all device terminals are configured for static forcing functions:
Open, Common, Voltage Bias, or Current Bias. Therefore, the range-dependent
delay may not be needed, because source settling time is not needed after the initial
application of current or voltage. You can set the delay to 0 s by setting the Delay
Factor to 0.
