Tool/software: Code Composer Studio

Hi

  I have a question about the AWR1843 TX power monitoring ,  in my test,only one tx channel is enabled , eg  TX0 is on and TX1 and TX2 is off, but the power monitor shows that every channel  has power, like the picture below ,  why does the TX power monitoring is not meaningful ?

thankyou

    Hello Edward,

    You will get thee async-event report (Tx0, Tx1, Tx2 power) only if all these are activated in rlRfAnaMonConfig API.

    Check that Tx1 and Tx2 bits are not set for this API rlRfAnaMonConfig. This API is used to enable any monitoring based on bit set.

    Hi

    I have set all three bit (Tx0 Tx1,Tx2) in rlRfAnaMonConfig API,  if only Tx0 bit  is set,then only one async-event report will get, but my question is how to understand the Tx power mornitoring result if the related channel is not  turned on?  In fact Tx1 and Tx2 channel is turned off, the mornitor result is meaningless  and  if  there is any  problem with front end ,  does the the Tx power morniror is relieable?

    Hello Edward,

    Each of Tx Power report has different Sub-block ID in the asynchronous event message. And Specific Tx report is available only if that monitor is enabled and triggered. So Tx power monitor is measured for requested Tx antenna and it is reliable.

    Monitor happens on those TX only which are turned on and requested to have measurement. 

     Let me know if you have any other query here.
