Selects the power definition type for the primary cell.
In multiple carrier case, Power Definition Type setting in each carrier should be same.
If Power Definition Type is set to Total Power, power reference is Amplitude parameter on Instrument node; RSTP and OSTP are automatically calculated.
If Power Definition Type is set to RSTP, power reference is RSTP; Amplitude parameter on Instrument node, Power parameter on Component Carrier, and OSTP are automatically calculated (CC Power becomes read-only).

Sets the Reference Signal Transmit Power, in dBm, when the Power Definition Type is RSTP. Otherwise, displays the Reference Signal Transmit Power (RSTP), in dBm and the value is updated after generation.
In case Power Definition Type is Total Power, RSTP is automatically calculated by Amplitude parameter in Instrument, Power parameter in Component Carrier, and each carrier signal settings.
In case Power Definition Type is RSTP, Amplitude parameter in Instrument and Power parameter in the Component Carrier is automatically calculated and the value is set as read-only.
Available setting range and step depends on hardware.
