Custom sweep
For a custom sweep, the user specifies the number of point in a sweep and the source level
at each point. Figure 12 shows a 6-point, 50% duty cycle pulse sweep. The specified
voltage level at points P0, P2, and P4 is 1V, while the voltage level at P1, P3 and P5 is 0V.
With the desired source (V or I) selected, use the following menu sequence to specify the
number of sweep points and the source level at each point:
Press CONFIG > press SWEEP > select TYPE > select CUSTOM
After selecting CUSTOM, these menu items will be displayed:
# POINTS — Use to specify the number of points in the sweep (1 to 2500)
ADJUST POINTS — Use to set the source level at each point in the sweep. The first point
in the sweep is P0000. After setting the level for P0000, increment the pointer to P0001
and set the level for that point. In a similar manner, set the level for each point in the
sweep.
INIT — This option allows you to set a consecutive range of sweep points to a specified
level. After selecting INIT, you will be prompted to enter the source VALUE, the START
PT (point), and the STOP PT (point). For example, if you want points 10 through 15 to be
1V, set VALUE to 1V, START PT to 10, and STOP PT to 15.
