* Any entry expressed in % (or converted to %) is subject to a limit of +/-1000%.
** Any entry expressed in ppm (or converted to ppm) is subject to a limit of +/-10000ppm
*** A phase deviation expressed in radians is a Deviation expressed as a ratio of the Rate, such that:
Phase deviation(rad) = Deviation (Hz) / Rate (Hz)
