Fig 5-4 Dynamic Load Current With Independent Programmed Rise/Fall Slew Rate - Prodigit 3110 Series Operation Manual

5.3.2 Dynamic mode:
The built-in pulse generators allow the user to recreate real world loads that vary
With time
Major application areas for dynamic operation in CC mode include:
• Power supply load transient response testing
• Power recovery time testing
• Battery Pulse load simulation
• Power component testing
• Two levels of current can be set and the rate of change between the 2 current
levels can be adjusted in relation to time. The current rise (slew) rate and the
current fall (slew) rate can be adjusted independently from each other and are
further defined below
• Rise slew rate = | Ilow - Ihigh | / Ta ( A/us )
• Fall slew rate
• Rise time
• Fall time
• Please see Fig 1-11 for more information on slew rates.
• The time the waveform is high (Thigh) and the time the waveform is low (Tlow)
can Also be adjusted. The diagram below shows the 6 adjustable parameters
that Define the dynamic waveform.

= ( Ihigh - Ilow ) / Tb ( A/us )
(Ta) = ( Ilow - Ihigh ) / Rise slew rate
(Tb) = ( Ihigh - Ilow ) / Fall slew rate
