AD9361 on a Zynq EVB demo - performance issues

I'm running the ADI IIO oscilloscope on a ZC706 with an AD FMCOMMS3-EBZ.

the RF connectors are connected in a loop (either RX1-TX1,RX2-TX2, or cross, RX2-TX1,RX1-TX2)

for any selected file (QAM,MSK etc) i can't get a propert performance, and the constellation view looks very bad, somtimes shifted in phase and most of the time just very noisy.

is there any script/default settings tutorial/refference that can be use to optimize settings and performance for this demo?
