Pulse Mode Sweeps - Tektronix KEITHLEY System SourceMeter 2636B Reference Manual

Section 4: Sourcing and measuring Series 2600B System SourceMeter® Instrument Reference Manual
When the sweep is started, the output level goes to the first point in the sweep. The sweep will
continue through the steps in the order that they were programmed.
The following figure shows a different example of a list sweep with six measurement points. When the
sweep starts, the current or voltage goes to the first point in the sweep. The unit cycles through the
sweep points in the programmed order.

Pulse mode sweeps

A pulse mode sweep can be created for any of the sweep types by configuring the end pulse action.
To configure a pulse mode sweep for source-measure unit (SMU) A, send:
smua.trigger.endpulse.action = smua.SOURCE_IDLE
To configure a DC sweep for SMU A, send:
smua.trigger.endpulse.action = smua.SOURCE_HOLD
Timers must be used to configure the pulse width and period. Refer to Using timers to perform pulse
mode sweeps (on page 6-15) for details.
The pulse width is managed by controlling the duration between the source stimulus event and the
end pulse stimulus event. Note that a latency exists between these stimulus events and their resulting
source level transitions. This trigger latency can vary based on factors such as the source range and
the electrical characteristics of the device under test (DUT).
