Logarithmic staircase sweeps
This sweep is similar to the linear staircase sweep. The steps, however, are done
on a logarithmic scale as shown in the example sweep in Figure 4-3. This exam-
ple is a 5-point log sweep from 1mA to 10mA. The sweep delay parameter deter-
mines the time period for each step. As with the linear staircase sweep, the sweep
delay period is the same for all steps.
