If the EUT is DC battery-powered and the side to which the test is applied has voltage, how should the fast transient/burst test be performed?

If the EUT is DC battery-powered and the side to which the test is applied has voltage, how should the fast transient/burst test be performed?

With our fast transient/burst simulators, almost no current from the battery flows through the coupling capacitor into the generator section, so it can be connected as is without issue.
