Carrier Wave Waveform Selection
PM carrier waveform can be: Sine wave, square wave, ramp wave or arbitrary wave (except
DC), and the default is sine wave. Press Carrier soft key to select carrier waveform.
Carrier Wave Frequency Setting
If you need to set up the carrier wave frequency,see Carrier Wave Frequency Setting
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
Param → Source → External in turn.
1) Internal Source
When modulation source is internal, modulation wave 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 Param → ModWave in turn.
Square wave: duty ratio: 50%
Rising ramp wave: symmetry degree 100%
Falling ramp wave: symmetry degree 0%
Arbitrary wave: limit the wave length to 4kpts through auto test count.
Noise: white gauss noise
