Figure 14.2 Modulation Interface - Rigol DHO900 Series User Manual

Function/Arbitrary Waveform Generator (for
DHO914S and DHO924S only)
TIP
Supported carrier types include sine, square, and ramp. When the selected carrier waveform is
not supported, the modulation function is not available. You need to select an available carrier
waveform in the "Basic waves" menu.
14.2.1 AM
Amplitude Modulation (AM), namely the amplitude of the carrier waveform changes
with the amplitude of the modulating waveform.
Select the Modulation Type
Click or tap the Modulation Type drop-down button to select "AM".
Select the Modulating Waveform
The instrument uses built-in signals for modulation. Click or tap the Shape drop-
down button to select the modulating waveform. Available waveforms include:
• Sine
• Square with 50% duty cycle
• Triangle with 50% symmetry
• UpRamp with 100% symmetry
• DnRamp with 0% symmetry
• White gaussian noise
Set the Modulation Depth
Modulation depth is a percentage that represents the amplitude variation. Click or tap
the Depth input field to set the modulation depth with the pop-up numeric keypad.
