A method that includes an electronic application identifying a downlink sequence for execution by a surface control system of a drilling rig, with the sequence including target output values of a mud pump system and/or a drive system. The method includes instructing the control system to operate in accordance with the sequence. The application receives measured output values of the mud pump system and/or the drive system and calculates differences between the target and measured output values. When the differences are within a level of tolerance, then the application identifies the control system as compliant; and when the differences are greater than the level of tolerance, then the application identifies the control system as non-compliant. The method also includes the application receiving data from a BHA of the drilling rig and determining, based on the data received, if a downlink to the BHA was successful.
