The carrier wave can be Sine, Square, Ramp, or Arbitrary wave (except
DC). Press , , , or to select a desired carrier wave
shap.
(3) Set carrier wave parameters:
Press the wave shap key of the selected carrier wave to display the
waveform and parameters of the carrier wave. You can change the
parameters of the carrier wave. Press Mode to return to the modulation
mode interface.
(4) Select modulating wave shape:
Press the Shape softkey, then press the Sine, Square, Ramp, Noise, or
Arb softkey to select the modulating wave.
(5) Set modulating wave frequency:
Press the PM Frequency softkey to set the modulating wave frequency.
The range is 2 mHz – 1 MHz (for internal source only).
(6) Set phase deviation:
Phase deviation is the deviation of the modulating wave phase relative to
the carrier wave phase. Press the Deviation softkey to set the PM phase
deviation. The range of phase deviation is from 0° to 180°.
FSK (Frequency Shift Keying)
Frequency Shift Keying modulation is a modulation technique that shifts the
output signal frequency between two frequencies: the carrier frequency and
hop frequency. The shift frequency (FSK rate) is determined by the internal
signal level. The FSK user interface is shown below.
