 When the carrier waveform currently selected is arbitrary waveform, please
refer to the introduction in “To Output Arbitrary Waveform” to set the
parameters of the carrier waveform currently selected.
To Select Modulation Source
DG1000Z can accept modulating waveform from internal or external modulation
source. Press Mod  Source to select “Int” or “Ext” modulation source.
1. Internal Source
When internal modulation source is selected, press Shape to select Sine, Square,
Triangle, UpRamp, DnRamp, Noise or Arb as modulating waveform. The default
is Sine.
 Square: 50％ duty cycle
 Triangle: 50％ symmetry
 UpRamp: 100％ symmetry
 DnRamp: 0％ symmetry
 Arb: the arbitrary waveform selected of the current channel
Note: noise can be used as modulating waveform but can not be used as carrier
waveform.
2. External Source
When external modulation source is selected, Shape and AM Freq will be
grayed out and disabled. The generator accepts the external modulating signal
from the [CH1/Sync/Ext Mod/Trig/FSK] connector at the rear panel. At this
time, amplitude of the modulated waveform is controlled by the ±5 V signal level
of the connector. For example, if the modulation depth is set to 100%, the output
amplitude will be the maximum when the modulating signal is +5V and the
minimum when the modulating signal is -5V.
