BIST tone test ad9361 using TxMonitor (RSSI)

Dear engineers and researchers,


I'm using FMCOMMS5 and Xilinx zc706, No-OS API. I want to generate a BIST test signal using ad9361_bist_tone(ad9361_phy, BIST_INJ_TX,3,0,0) and directly couple that tone to TXMON_1(or2) port using an RF cable connector. so that I can measure the incoming signal power level. I have some questions:

1. Is it safe to connect TX and TMON port directly using a cable?

2. If not then what I have to do if I want to measure the power level in that fashion? 

3. In this case is it useful to use the ad9361_set_tx_attenuation function, or I can manually control the gain at the RX during the RSSI measurement? 


Thank you,
