(2) Press to display the waveform and parameters of the current carrier.
You can change the parameters of the carrier. For details, please refer to
Output Sine Wave on page 10. Press or Mod to return to the
modulation mode interface.
(3) Press the FSK Rate softkey to set the 3FSK rate, which can be set from 2 mHz
to 1 MHz.
(4) Press the Frequency Hopping 1 Frequency Hopping 2 softkey to select the
setting frequency hopping, which is the alternating frequency.
Quaternary frequency shift keying (4FSK)
Using quaternary frequency shift keying modulation, the output frequency is shifted
between four preset frequency values ("carrier frequency" and 3 "hopping
frequencies"). The frequency at which the output moves between the four
frequencies is determined by the internal frequency generator (internal source). The
carrier wave can be a sine wave, a square wave, a ramp wave, or an arbitrary wave.
The user interface of quaternary frequency shift keying modulation is shown in the
figure below.
