Adrv9026 rx tia and rx qec calibration failed

Category: Software
Product Number: adrv9026

1. 90-NLS  Choosed
2. During the initial calibration process of ADRV9026, if rx tia or rx qec calibration items are selected, the calibration cannot pass;
3. When only a few calibration items are selected, the calibration is passed and the jesd link is successfully established;
4. At this time, only one signal is connected to the RF port, but four RX AD signals with waveforms are found on the FPGA ; Only one channel displays the waveform of the external input signal, while the other three channels display waveforms with fixed frequencies (approximately 20.48 MHz).

Thread Notes

  • There should not be a any signal present at the RX input while running the init cals or during the chip initialisation.

    QEC and TIA cals will generally fail due to the RF matching. Please check this part.

    I hope you did not modify the profile and using as it is. 

    Please share complete log for further help.
