Hi RahulMushini 

Thanks for sharing the documents, while enabling the DPD in the GUI the number of iterations goes on increasing in the GUI but i'm getting nothing in the signal analyzer. I'm following the steps that are given in the doc that i have shared.
Kindly suggest the set of steps or any modifications that i need to do.

Regards,

Anurag

Hi Anurag,

1) Avoid loading the previous version of the Taxidi file. Please reconfigure TES manually with the required settings.

2) Have you checked the peak power at the ORx port? The ORx attenuation is triggered based on this value, which can impact DPD performance. I assume you have used the provided Python script to obtain the path delay value.

3) Capture the signal without DPD and review the gain vs. input signal plot to determine the PA compression. We recommend compressing by approximately 1 dB.
