1.1.5. Dynamic Waveform Definition

Along with static operation the 34000A Series Electronic Load 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 34000A Electronic Load.

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 1-6.

The dynamic waveform can also be set up via the optional computer interface. Dynamic

waveform settings made from the front panel of the load module can also be saved in the

memory of the 34000A series Electronic Load. For the store/recall procedure and the computer

command set please refer to the relevant operating manual for the 34000A series Electronic Load.

The analogue programming input also provides a convenient method of implementing a dynamic

waveform. Please see the section 3.1.26 titled 'Analog Programming Input' for further information.
