To Select Modulation Source
The SDG6000X can accept a modulating signal from an internal or external
modulation source. Press Source
to select “Internal” or “External” modulation
source. The default is “Internal”.
1. Internal Source
The way of setting internal source is similar to AM.
2. External Source
When external source is selected, width deviation (or duty cycle deviation) is
controlled by the signal level of the [
Aux In/Out
] connector at the rear panel. For
example, if the width deviation is set as 10 s, +6 V signal level corresponds to
10 s width change.
To Set Pulse Width/Duty Deviation
Press Width Dev (or Duty Dev) to highlight the parameter, and use the
numeric keyboard or arrow keys and knob to input the desired value.
Width Deviation represents the maximum variation of the modulated
waveform pulse width relative to the original pulse width.
The width deviation cannot exceed the current pulse width.
The width deviation is limited by the minimum pulse width and current
edge time setting.
Duty Deviation represents the maximum variation (%) of the modulated
waveform duty cycle relative to the original duty cycle.
The duty cycle deviation cannot exceed the current pulse duty cycle.
The duty cycle deviation is limited by the minimum duty cycle and current
edge time setting.
Duty deviation and width deviation are correlative. Once a parameter is
changed, the other will be automatically changed.
Note:
Setting parameters of PWM is similar to AM.
