Logarithmic staircase sweep
This sweep is similar to the linear staircase sweep. The steps, however, are done on a
logarithmic scale. The symmetrical log points for the steps are determined by the specified
number of sweep points. Figure 11 shows a 5-point log sweep from 1 to 10V.
With the desired source (V or I) selected, use the following menu sequence to set the start
and stop levels, and the number of sweep points (2 to 2500):
Press CONFIG > press SWEEP > select TYPE > select LOG
After selecting LOG, you will be prompted to enter the START and STOP levels, and the
NO OF POINTS.
