AWRL6432BOOST: Question about antenna radiation patterns (LBK Gain ?)

Champ,

From the EVM user guide, can you explain about "LBK Gain (dBcode)"?

How to calculate LBK Gain in the antenna radiation patterns as below?

Best regards,

Hayden

    Hi Hayden, 

    LBK refers to loopback gain measured between each TX to RX. I have looped in Zigang to help you with details.

    Hi, Hayden:

    We placed the EVM on a rotator and placed a target at bore sight.   Then we control the motor on the rotator to scan different angle in azimuth direction. For each angle,  raw data is captured and the peak signal power from the target range is recorded for each visual antenna.  Then we plot the loop-back gain cross angle for each TX-RX pair.  

    Then we change the EVM mounting by 90 degree, and again put on the rotator to cover elevation gain pattern. 

    Hope this helps.

    Best,

    Zigang
