CONTROL settings
Internal generator power Level
You can set the output power level of the internal function generator to between
0 and 100%. Use the slider or the field in the upper right corner of the Level slider
to adjust the modulation level.
Internal generator Offset
The offset of the internal modulation signal can be adjusted between -100 and
+100% dependent on the modulation level. For example, if the modulation level is
set to 40%, the offset can be adjusted between -60 and +60%. The sum of
modulation level and the absolute offset can be a maximum of 100%.
Integrating Update Interval
The integrating update interval sets the update interval for a software integrating
function. The function is only available on X15 systems with Coupling configured
as DC and Range set to Narrow .
Turning on wavelength modulation
To enable wavelength modulation, in the status panel lower right click the WL
mod button. The indicator next to the button turns ON green. Clicking the button
again once turns of the feature.

The laser output controls can be set to either Power or Current mode as
described in “.Operating mode” on page 25 . Click the menu item shown in
Figure 43 to toggle the mode. The Control panel will automatically switch to the
