Sweep delay
The sweep delay parameter determines how long the Model 622x will remain on
each sweep step once the output current is set to the step value. For linear and
logarithmic staircase sweeps, the sweep delay period is the same for every step in
the sweep. For customs sweeps, the sweep delay for each step can be indepen-
dently programmed.
The programmable range for the sweep delay is from 0.001s to 999999.999s.
