Configuring Power or Delta Current
Configuring Power or Delta Current
Values appearing on the display correspond to:
³
the actual value on the source port obtained in Normal and Dither
Modulation modes at selected wavelength
OR
³
the delta obtained after switching to High Wavelength Stability and
On/Off modes).
Adjustable parameters depend on the control mode:
³
Normal and Dither modes: to adjust the source power. Relative value is
only available for these modes.
³
High Wavelength Stability and On/Off Modulation modes: once you
have set the desired power in Normal mode, you can use these modes
to enhance wavelength stability at the established value (permitted
tuning range: ±1 mA for temperature/wavelength).
³
In all modes, modifying the power current also modifies the internal
laser temperature. The source then takes a few seconds to adjust to
the new value and a message will be displayed.
The main window data display differs for each control mode.
