tional data points. The EOF defines the end of the pattern. A pattern produced using the Pattern
Generation window (Figure 10) can be saved in this format using the Pattern Export File Select button.

1.2.2 PATTERN GENERATION WINDOW
The Pattern Generation window (Figure 10) allows a user-specified program of up to 250 points to be gen-
erated. This method of generating complex patterns, allows rigorous testing of a UUT (Unit Under Test),
within the boundaries determined by the power supply and the load conditions.
The GENERATED POINTS window shows the number of points currently included in the list for each of
the three parameters, CURRENT, VOLTAGE and DWELL. The CLEAR LISTS button clears all points in
the list (individual points can be edited, but not deleted once they have been added).
FIGURE 10. PATTERN GENERATION WINDOW
There are two choices for DESTINATION: CURRENT or VOLTAGE. This determines what type of wave-
form to generate. The four waveform choices are LEVEL, SINE, TRIANGLE and SQUARE. Waveforms
may consist of a single segment, or multiple segments, each defined separately (see PAR. 1.2.3 for
details).
NOTE: The values chosen for Amplitude and Waveform Offset must be within the limits estab-
lished by the Model settings windows.
With the MODE SELECT switch set to VIEW, the parameters for each point can be viewed, but not
changed. The values displayed apply to the point indicated in the Point Number window. Use the
< and >
buttons to navigate through the list or enter a number directly in the Point Number window and press
ENTER on the computer keyboard to get to a specific point. By changing the MODE SELECT switch to
EDIT, values for existing points can be changed by entering a new value for any of the parameters.
As an example, if a five point list was to be entered, where all the values were the same except the volt-
age, the list could be initially generated by specifying 5 points (which will all be identical), then setting the
MODE SELECT switch to EDIT and using the
< and > buttons to view and edit the voltage for each point
