I would like to determine the path delay between modulator and demodulator in order to set the correct Phase reference in the demodulator using the delay_path() function. In the documentation it says that I can use two TimedSink components to specify the start and end path, but when I do that I get the error:

Function "delay_path" : This function is only valid for 1-Dimensional Data.

But T1 and T2 time sink components are by definition Voltage vs Time (2-dimensional). Probably the documentation is correct, but I don't understand what I am doing wrong. I would appreciate your help again!

Have you tried the MeasuringDelay design under the BER_Validation_prj example project?
