The diagram in A2.14 of the SPI reference seems to indicate that the RxTSP's digital RSSI samples the signal strength before the AGC block:

This is inconsistent with the following diagram in the main data sheet that indicates that RSSI is sampled after the gain is applied

Either mode of operation could make sense here, but it'd be good to be consistent in the diagrams.
