Sweep waveforms
There are three basic sweep types to select from: linear staircase, logarithmic staircase,
and custom, as shown in Figure 5-3.
Staircase sweeps
The linear staircase sweep goes from the start level to the stop level in equal linear steps.
The logarithmic staircase sweep is similar except it is done on a log scale with a specified
number of steps per decade.
Custom sweep
The custom sweep lets you construct your own sweep by specifying the number of mea-
sure points and the source level at each point. See Section 9 for more details on sweep
operation.
