512 - Each point is measured 512 times with the average taken as the
final value.
Pulse Mode
In pulse mode, the pulsed rather than continuous current or voltage can be
applied to the specified channel of the DUT to prevent the DUT from overĆ
heating.
Pulse is characterized by the parameters of pulse period, pulse width, base
offset (pulse peak value is maintained in this case), hold time and delay
time. Figures 3Ć9 and 3Ć10 show a comparison between a pulsed sweep and
a normal sweep. In the case that the pulse voltage is supplied to the gate of
a FET, for example, the base offset can be used to set the base voltage to
below the cut off voltage so that the drain current does not flow except
during the time of pulse width.
