Sample :STEP Pulse measurement
Pulse sequences — rising and falling
Consider the pulse form in Figure 3-8. This pulse form has three falling (DOWN) level steps
followed by three rising (UP) level steps. Since these steps rise and fall to the same steady state
current, acti
ve steps need to be designated as 6 UP and 0 DOWN to measure the step level cur-
rent. If DOWN steps are specified then, the step level current measured will be the steady state
current.
