 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 ModSource 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.
