Fig 5-4 Dynamic Load Current With Independent Programmed Rise/Fall Slew Rate - Prodigit 33501 Series Operation Manual

5-4 PRODIGIT
2. Dynamic mode:
I. Built-in Pulse generator: (Fig 5-4)
Major application:
a. Power supply load transient response testing
b. Power recovery time testing
c. Pulse load simulation
d. Power component testing
Description:
The maximum Rise/Fall current slew rate or minimum Rise/fall time is the time required for
the load input to change from 10% to 90% or from 90% to 10% of the programmed High to
Low load level.
Rise slew rate = | Ilow - Ihigh | / Ta (A/us)
Fall slew rate = ( Ihigh - Ilow ) / Tb ( A/us )
Rise time = Ta = | Ilow - Ihigh | / Rise slew rate
Fall time = Tb = ( Ihigh - Ilow ) / Fall slew rate
ii.Analog programming input: ( Fig 5-4 )
Major application:
a. Simulate real load condition
b. Battery discharge testing
