MODULATION
141
Frequency Shift Keying(FSK)
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 internal rate
generator or the voltage level from the Trigger INPUT terminal on
the rear panel.
Only one modulation mode can be used at once. When FSK
modulation is enabled, any other modulation modes will be
disabled. Sweep and Burst also cannot be used with FSK
modulation. Enabling FSK will disable Sweep or Burst mode.

Selecting FSK Modulation
When using FSK mode, the output waveform uses the default
settings for carrier frequency, amplitude and offset voltage.
