This provides an option to calibrate the full system by compensating for phase differences in the antenna coax cables.

`touchtone` - You can output .s1p files for the 5 coax cables in your system, and add them to the _calibration folder. Name them as cable_ch0.s1p, cable_ch1.s1p and so on. You need to ensure that the touchstone file covers the frequency range that you will be using.
