3. Configure the electronic load in current control dynamic mode with the settings listed in the
following table.
4. Configure the oscilloscope to acquire a waveform according to the settings listed in the
following table.
5. Configure the NI PXIe-4154 according to the settings listed in the following table.
6. Measure the transient response recovery time and transient response dip, as displayed in
Figure 10. The transient response recovery time is measured from the time the dip begins
until the time at which the waveform crosses above the final voltage minus 20 mV.
