Transmit and Receiver Information (continued)
RSSI
The RSSI value is a measure of the RF input power that is sampled on the low-high transition of the PX_ON
signal. The RSSI value is sent out on the SI-CDO line when the channel register is accessed (same address).
Select, for example, receive channel 50 (channel register = 10110010) and input a GFSK modulated carrier
(–60 dBm). Toggle PX_ON low-high-low and read out the RSSI value by accessing the channel register once
again. The RSSI value will be in the 6 to 14 range. Input a higher power (–40 dBm). Toggle PX_ON and read out
the RSSI value again. The RSSI value will be in the 20 to 28 range.
