ad9361.iiostream.c example on adrv9361-z7035

Dear all,

I compiled the the ad9361 iiostream.c example and executed it successfully with default bandwidth, central frequency and sample rate. Frequency provided to adrv9361-Zc7035 by signal generator at RX1a with 0dbm level and displayed this signal on spectrum analyzer from channel TX1a. But the signal level of transmitted signal was very low -80dbm . I verified the signal generator and spectrum analyzer for functionality by connecting direct to one another . So the cable and equipment were correct .

Now I want to know that how I can increase signal level of the transmitted signal or what is the issue.
