FSK Hop Frequency
The default Hop frequency for all waveform shapes is 100 Hz. A
square wave with a duty cycle of 50% is used for the internal
modulation waveform. The voltage level of the Trigger INPUT
signal controls the output frequency when EXT is selected. When the
Trigger INPUT signal is logically low the carrier frequency is output
and when the signal is logically high, the hop frequency is output.
