Description
Types
AM
Select AM
Signal source Internal/external
Select internal modulation/external modulation
Internal
modulation
Frequency
Set modulation wave frequency (2mHz~20kHz)
Depth
Set amplitude variation depth (0%~120%)
Modulation wave
Select internal modulation signal
Sine/Square/Triangle/UpRamp/DnRamp
External
modulation
Depth
When selecting external modulation, the modulation signal
can be input by the [Modulation In] on the rear panel, and
only Depth needs to be set here.
Note:
Modulation depth refers to amplitude variation range (also called Percentage Modulation)
settings. Modulation depth can vary from 0% to 120%.
Modulation at 0%, the output amplitude is half of the specified value.
Modulation at 100%, the output amplitude equals to the specified value.
Modulation at 100% above, the output of the instrument will
not exceed 20Vpp.
