#Precondition: Please edit the path defined by DPD_MODEL_FILE in line 36 to point to the correct location before running this script
#Description: This script aborts DPD tracking cal on all 4 Tx channels and saves the last set of coefficients from the requested Tx channel 
# on the ADRV9025 device, that was computed prior to disabling the DPD tracking cal.
# The coefficients are saved in the format shown below
