Hello! I want to perform EVM test of LTE20M signal with ZED board + FMCOMMS3 hardware and ADI_IIO_Oscilloscope GUI. for that I made a loop from TX1A to RX1A, chose LTE20M waveform from pop-up menu, chose LTE20MHz FIR filter. I can see a nice LTE signal in frequency domain, but i don't see constellation and consequently EVM. What settings should I change in order to get clear constellation with any of existing waveforms in IIO Oscilloscope?

Best Regards.
