Figure 28 Wavelength modulation - source selection
Source (modulation)
When using CONTROL to set the wavelength modulation source, perform the
following.
1. Select and highlight the desired module in the Device Selector panel.
2. From the Settings drop down menu, select Wavelength modulation .
3. Set the source for the module to either Internal , External or Both. See
Figure 29 .
•
Internal – wavelength is modulated using the module’s internal function
generator.
•
External – wavelength is modulated by the signal on the bus set by the
ACOUSTIK controller setting.
•
Both – both internal and external signals are used simultaneously to
modulate the wavelength.
