To Select Modulation Source
The SDG6000X can accept a modulating signal from an internal or external
modulation source. Press Mod
→ AM → Source to select “Internal” or
“External” modulation source. The default is “Internal”.
1. Internal Source
When internal modulation source is selected, press Shape to select Sine,
Square, Triangle, UpRamp, DnRamp, Noise or Arb as the modulating
waveform.
Square: 50% duty cycle
Triangle: 50% symmetry
UpRamp: 100% symmetry
DnRamp: 0% symmetry
Arb: specified arbitrary waveform
Note:
Noise can be used as modulating waveform but cannot be used as carrier.
2. External Source
When external modulation source is selected, the generator accepts external
modulating signals from the [Aux In/Out] connector at the rear panel. At this
time, the amplitude of the modulated waveform is controlled by the signal level
applied to the connector. For example, if the amplitude of the external
modulating signal is 12 Vpp, the AM modulation depth will be 100%. The
output amplitude will be the maximum when the modulating signal is +6 V and
the minimum when the modulating signal is -6 V.
Key Points:
How to achieve modulations within the two channels? The SDG6000X can
use one channel as a modulating source for the other channel. The following
example takes the output signal of CH2 as the modulating waveform.
1. Connect the CH2 output terminal to [Aux In/Out] connector on the rear
panel using a BNC cable.
2. Select CH1 and press Mod to select the desired modulation type, set the
