Prodigit 3310F Series - Fig 1-8 Constant Voltage Mode; Fig 1-9 Constant Power Mode

4 PRODIGIT
1.1.3. CV Mode:
At Constant Voltage mode, the 3310F series Electronic Load will attempt to sink enough
current until the load input voltage reaches the programmed value (see Fig 1-8).

1.1.4. CP Mode:
At Constant Power mode, the 3310F series Electronic Load will attempt to sink load power
(load voltage * load current) in accordance with the programmed power. (see Fig 1-9).

1.1.5. Dynamic Waveform Definition
Along with static operation the 3310F load modules are built with a Dynamic mode for
operation in Constant Current (CC), Constant Resistance (CR) or Constant Power (CP).
This allows the test engineer to simulate real world pulsing loads or implement a load
profile that varies with time.
A dynamic waveform can be programmed from the front panel of the 3310F load module.
The user would first set a High and low value of load current using the Level button. The
Dynamic Setting then allows for the rise and fall time between these 2 current values to be
adjusted. The time period that the waveform is high (Thigh) along with the time period that
the waveform is low (Tlow) can also be set.
The dynamic waveform is illustrated below in Fig 1-10.
