Frequency Shift Keying (FSK) Modulation
(AFG-2100 Series)
Frequency Shift Keying Modulation is used to shift the frequency
output of the function generator between two preset frequencies
(carrier frequency, hop frequency). The frequency at which the
carrier and hop frequency shift is determined by the rate setting or
the voltage level from the Trigger input port on the rear panel.
FSK modulation is only applicable to the AFG-2105, AFG-2112 and
the AFG-2125.
