Press Parameter→ Frequency softkey to enter carrier wave frequency setting, then enter required
numerical value, and select unit.
Modulation Source Selection
This device can select internal modulation source or external modulation source. After enabling PM
function, the default of modulation source is internal. If need to change, press
Parameter→ModulationSource→External in turn.
1) Internal Source
When modulation source is internal, modulation shape can be: sine wave, square wave, rising ramp
wave, falling ramp wave, arbitrary wave and noise. After enabling PM function, the default of
modulation wave is sine wave. If need to change, press Carrier Wave Parameter→Type in turn.
2) External Source
When modulation source is external, carrier waveform will be modulated by an external waveform. PM
phase deviation is controlled by ±5V signal level of external modulation input terminal on front panel.
For example, if phase deviation value in parameter list has been set to 180º, +5V of external
modulation signal is equivalent to 180º phase shift.
