Figure 70: 2470 sweep linear staircase

Logarithmic staircase sweep

A logarithmic staircase sweep is similar to a linear staircase sweep. The only difference is that the

steps are scaled logarithmically.

The steps in a logarithmic staircase sweep increase or decrease geometrically, beginning with a start

voltage or current and ending with a stop voltage or current. The figure below shows an increasing

logarithmic staircase sweep.
