000Ch (RC Threshold)

This object stores the RC detection threshold value, expressed in 100*dBµV.

The RC message is considered valid only if the SRC > NRC and SRC is greater than the RC

detection threshold parameter. (Refer to 2. chapter Repeater Call, Heading 1).

The confirm message of a CMD_ReadDBRequest will return the current value without

changing it. The CMD_WriteDBRequest will set the threshold value and the confirm

message will return the value.

Read/write confirm data format:

The same as request.

6.5.14

000Dh (S0, N0, PGA)

This object stores the Signal and Noise amplitude values measured for frequency f0 and the

PGA gain set during the last CMD_DataIndication.

Refer to Section : Raw estimation to convert the returned codes for N0 and S0 to electrical

values measured in dBµV.

Write request data format:

As this parameter is read-only, the CMD_ReadDBRequest can be used, the

CMD_WriteDBRequest cannot.
