the Slope is set to Negative.
(6) Press F4 to set Phase Deviation. Carrier waveform phase shifts to the modulating
phase with the specified PSK rate, and then returns to the original phase.
Term Explanation
PSK Rate:
The rate at which the output phase sh
ifts between the carrier phase and the
modulating phase is called the PSK rate (Internal Modulation only).
To Generate Sweep
Sweep function is only used for CH1. In the frequency sweep mode, the generator "steps"
from the start frequency to the stop frequency at the sweep rate you specify. Sweep can
be generated by Sine, Square or Ramp Waveforms.

How to set the parameters of Sweep
(1) When the output signal is Sine, Square or Ramp waveform, press the Mod button,
then press F2 to select Sweep to enter the Sweep mode.
(2) Press , or button to choose the waveforms. Take Sine for
instance, press to display the waveform and parameters. You can change the
parameters, please refer to To set signals on page 12. Press button again to
return to the Sweep mode interface.
