Sweep characteristics
Linear staircase sweeps
As shown in Figure 5-2, this sweep type steps from a start voltage or current value
to an ending (stop) value. A measurement is made at each step after a specified
delay period (settling time). Programmable parameters include the source
function, channel, start and stop levels, the number of sweep points, and the
delay (the time between source and measure at each step). The step size is
determined by the start and stop levels, and the number of sweep points:
step = (stop - start) / (points - 1)
