Hi,
I am trying to implement ADC DAC loopback with ADRV9001 transceiver as a channel between Signal Generator and Spectrum Analyzer for ZCU102 eval board. For this i have done a simple setup as follows:
Baseband Processor(ZCU102 evaluation board) <---------- ADC <------------SIGNAL GENERATOR
Baseband Processor(ZCU102 evaluation board) -----------> DAC ------------> Spectrum Analyzer
For this i have sent modulated rf signal (QPSK 1 Msymb/s) to adrv9001 adc and observed on the ILA at adc_1_data_i0 and adc_1_data_q0 in vivado. I have attached the waveform for your reference. After that i have sent the signal through FIFO to the
to the axi_adrv9001 ip's ports : dac_1_data_i0 and dac_1_data_q0 and i am trying to see if the loopback works. But i keep getting a single tone at the dac output as seen in spectrum analyzer. I suspect some configuration issue with respect to c side files. The mode was set to DDS in my headless.c file. Please suggest if any changes or modification required to see a modulated signal in the spectrum analyzer. and also let me know if any further information u want to know.
regards,
Anurag
