3.3.5 Inrush Current
Inrush current transients occur when the terminal is:
l First powered on.
l Preparing for transmit. This is when the terminal switches its internal voltage rail to a higher voltage for
transmitting.
l Terminal starts to transmit. This is when the terminal's power amplifier is turned on.
