(1) After pressing the Mod function key, press the modulation type soft key, use
the knob to select, the modulation type is 4FSK, press the enter key. The
carrier waveform can be selected as needed. The following is a sine wave.
(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 FSK Rate to set the 4FSK rate from 2 mHz to 1 MHz.
(4) Press Frequency Hopping 1 Frequency Hopping 2 Frequency Hopping 3 Soft
Key to select the setting frequency hopping, which is the alternating
frequency.
Binary phase shift keying (BPSK)
The use of binary phase shift keying modulation shifts the output phase between
preset frequency values ("carrier phase" and "modulation phase"). The frequency at
which the output moves between the two phases 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 the two-phase phase
shift keying modulation is shown in the figure below.
