Sequence Step
Trigger
Setting a trigger will instruct the SMU to wait and monitor for a DIO input
signal or remote command to be received to trigger start of the sequence.
Delay
The delay action will set a time delay before starting the sequence, this will
occur after the trigger, if set.
DIO Output signal
The SMU will set the assigned DIO output pins to either Logic High [5V] or
Logic Low [0V] before the main setup is run. Step 1 can be set High or Low, step
2 onwards can be set to Ignore, High or Low.
Setup
The setup is the main body of the sequence step, a setup (.stp) file must be
created prior to creating a step and loaded into the setup menu before any
actions or conditions are added to build the step.
Conditions
Conditions are linked to the loaded setup and measured
results, the SMU constantly monitors activity for set
conditions, if a condition is met an action will be activated. Up
to three conditions can be applied to each step, each
condition is assigned a single action.
A condition can be set to the following:
Level - Monitor for a set level(V,A,W, or
Ω)
including <= or=>
than a set level, within two set levels or outside of two set
levels.
Timeout - Run for a specified period of time.
External Input trigger - Monitor for an external trigger via
remote command or DIO.
Actions
Actions are assigned to conditions; any action can be added to
any condition, the same action can be used multiple times.
The action will activate when the assigned condition is met, if
the condition is not met, the action will be ignored.
An action can be set to the following:
Jump to step - Jump to a pre-defined step or next step in the
sequence.
DIO output level - Set DIO output pin as Logic High [5V] or
Logic low [0V]
Stop – Stop the sequence
Repeat
This will repeat the entire step a set number of times.
