Using the Sequence Wizards to Create a Sequence File
Sequence Wizards simplify the process of creating sequences by letting you enter voltages and currents directly for each step of
the sequence. A sequence can contain up to 20 steps, with settings for up to 8 channels. These settings, and all the programming
instructions necessary to automatically set up each channel, are stored in a Sequence file with a .seq extension.
Simple Sequence Wizard
The Simple Sequence Wizard lets you apply/measure DC current and voltage. To use the Simple Sequence Wizard:
1.
Open the Sequence software if it is not already opened.
2.
Select
Tools > Simple sequence wizard.
The Wizard interfaces contain tabs for each step (
Figure 4
). When you launch a
wizard the settings for Step A will be displayed. Click on any step’s tab to view that step’s settings.
3.
In the
Step Name
field, enter a name which easily identifies the step. The name must begin with a capital letter and
contain only letters, numbers, “.” or “_”.
