Rx Information and PA Detector Information
Figure 16
RSSI, Packets Counter and PA Detector Information
When you click Update, the following are read from the DUT:
•
•
RSSI values (signal strength) for each of the three Rx antennas (in dBm)
•
Packets received counters (PHY level) - There are two readings:
– the upper is for the number of packet received in the modem
– the lower is for the number of packets received in the modem with CRC error.
– the upper is for the number of packet received in the modem
– the lower is for the number of packets received in the modem with CRC error.
•
Packets received counter (MAC) - This counter is not used.
•
PA voltage - Returns the power indication from the PA detector during transmissions.
The PA detector information enters the BB chip through an 8 bit A/D. The reading in the DUT GUI is an average
of several readings and the numbers are on a scale of 0-255. Usually, each step represents approximately 10 mV.
