The configuration process communicates with the Xilinx RFdc Linux driver API running on the Processing
System (PS) APU of the RFSoC, providing runtime interaction and monitoring of the data converters. For
reference, the Xilinx RFdc source files are publicly available on GitHub

We can now re-enable the TX driver and PA of the Qorvo card.
Type ‘

0
’ to enable the TX
TQL9092 driver amplifier in channel 1 of the Qorvo card.
Channel 1 TX signal chain of the Qorvo card has been re-enabled, while the digital attenuators remain at
maximum attenuation. Refer to
We now proceed to configure the RF-DAC to generate a CW Tone for the Qorvo card.
