Step (voltage sweep)

The current size of each step of the sweep. The current level changes in equal steps of this size from

the start level to the stop level. A measurement is made at each source step (including the start and

stop levels).

Clarius never steps the force current beyond the value specified by the stop parameter, even if you

specify a step value that is larger than the stop value.

Use a step value that does not result in a fractional number of data points. If the data point is

fractional, the step value is forced to a value that results in a whole number of data points. To

calculate the data points:

For example, if Start = 0 A, Stop = 0.005 A, and Step = 0.0015 A:

This results in a data point value of 4.333. In this case, the Step value is forced to 0.001 A, which

results in four data points at 0 A, 0.0015 A, 0.0030 A, and 0.0045 A.

The number of data points that will be measured. This value is calculated by Clarius using the

information entered for the Start, Stop, and Step parameters, using the equation:

Points (log sweep)

The number of data points that the sweep will generate. Clarius uses the start, stop, and data points

to calculate the step size and forcing values according to the formulas:

Select Enter Values to open a dialog box in which you can type the current or voltage level for each

step of the sweep in the rows. You can type any valid instrument current or voltage.

You can select a value or multiple values in the list and copy, cut, or delete them. Use Paste to add

values that you copied or cut to a new location in the list.

Note that you cannot have blank rows in between values.

You can use the Ctrl key plus mouse selections to pick selected rows, then use the buttons to copy,

cut, or delete those rows. Note that when you paste the rows, any skipped rows are ignored (there

will be no blank rows).

You can use the Shift key plus mouse selections to pick a range of rows. When you paste the rows,

any blank rows are ignored.
