Product Number: ADRV9009
Hello,
I’m using a ZCU102 and ADRV9009 evaluation board to test functionality and performance.
While checking some signals using IIO Oscilloscope, I noticed a signal at the center that looks like DC offset.
The attached screenshot shows the signal when no input signal is applied.
According to the user guide, DC offset calibration runs at initialization, and DC offset tracking calibration can be enabled later.
However, I couldn’t find any option for enabling this tracking calibration in IIO Oscilloscope.
How can I activate this calibration?
Or is this DC offset something normal for ADRV9009 and not removable?
Thanks and Regards,
Eunseon Yu
