Is the reported RSSI value in SmartRF studio 7 actual value of received power or do we have to add offset for getting the actual value?

    The RSSI displayed in the "Continuous RX" and "Packet RX" modes have been compensated by the RSSI offset value (e.g. 73 for CC2530). If you read a value from the RSSI register, however, you need to add the offset.

    starts at the "Continuous TX" mode and select the "unmodulated",the reciever starts at the "Continue RX" mode.I can measure a sine wave of 2.4GHZ at the SAM antenna pin of the transmitter,but why cannot I measure any signals at the SAM antenna pin of the reciever? if I want to measured the signals of the receiver,how should I modify the registers? thanks very much
