SDM cycle during sweeps
An SDM cycle is performed on each step (or point) of the sweep. Thus, one measurement
will be performed at each step (level). The time spent at each step (level) depends on how
the SDM cycle is configured (i.e., source delay, measure speed) and the trigger delay (if
used).
Typical sweep applications
Typical applications for staircase sweeps include photodiode I-V curves. The custom
sweep can be used to configure a pulse sweep with a 50% duty cycle. For example, a 10V
pulse sweep can be configured by programming the odd numbered points for 10V and the
even numbered points for 0V. When the sweep is run, the output will alternate between
10V and 0V.
Sweep data storage
For a sweep that has a finite sweep count, the data will automatically be stored in the
buffer. This data can be accessed from the front panel or sent to a computer (remote oper-
ation) for evaluation (plotting). Statistical information on readings stored in the buffer are
also available from the front panel or via remote.
