TDR option in DPE UI

Hi ,

I want to deskew the delay in a cable which is connected from HSDIO 6571 to DUT. So for finding the TDR in DPE 2019 there was a option TDR in the instrument tab in 2019 version. BUt the same I couldnt find it on 2021 version. Please help me where I can find the same instead of Labview VI.

Thanks,

Arjun
