The S-meter on all Flex radios is calibrated like a RF spectrum analyzer to S9 = -73 dBm = 50 uV, so what you are seeing ins actual power in the RX pass band.
Since you are seeing integrated power, the size of the RX filter is a determining factor. If you are using a 3K filter, change it to 500 Hz and notice the reduction in signal power (strength). Also other radio's S-meter is effected by the RF gain and AGC. Not so with the FlexRadio SDRs. These factors can account for the difference.
