Details
This command is used to perform a staircase sweep. The linear step size to sweep is set using the
startv, stopv, and NumSteps parameters. The linear step size for the sweep is calculated as
follows:
The sweep can step forward (low voltage to high voltage) or it can step in reverse (high voltage to low
voltage).
The delayTime parameter sets the delay that occurs before each measurement. Note that there is
an inherent system overhead delay on each step of the sweep.
Use the setfreq and setlevel commands to set the AC drive frequency and voltage for the
sweep.
Use the dsweepv command to do a dual linear staircase voltage sweep.
