Setting the FSK Source
The AFG-2000 accepts internal and external FSK sources, with
internal as the default source. When the FSK source is set to internal,
the FSK rate is configured using the FSK Rate function. When an
external source is selected the FSK rate is equal to the frequency of
the Trigger input signal on the rear panel. When the input signal is
logically low the carrier frequency is output and when the signal is
logically high, the hop frequency is output.
