Verifying the Power and Voltage Levels
Verifying the Power and Voltage Levels
In the
Referencing
window, the power control bars only provides an indication of the
power, allowing you to adjust the magnitude of the inputs/outputs of your setup before
launching scan measurements.
The power levels depend on the current wavelength and power output of the TLS, and on
the characteristics of the component inserted between the output and the detector array of
the instrument. If the current wavelength provided by the TLS is filtered out by the
component, there will be no power on the detector array.
The
Power Monitoring (dB)
area enables you to monitor:
Optical power on all the detectors
Optical power at the output port of the CT440
The
Voltage Monitoring (V)
area enables you to monitor the voltage at the analog
Analog In
BNC input port on the rear panel.
To verify power and voltage levels:
In the main window, click the
Referencing
button.
The
Power Monitoring
area displays the power level in dB and the
Voltage Monitoring
area displays the voltage level on the
Analog In
BNC:
Green color represents acceptable optical power level on the output port and on the
detectors.
Blue color represents acceptable voltage level on the
Analog In
BNC input located on
the rear panel.
Red color indicates that the power and voltage values are out of specification for a
proper measurement with the CT440. In this case, verify that your laser injects enough
power into the CT440 and that your fiber connectors are clean (see
).
If you start any other action (scan, transfer function visualization …), the power
measurement provided here is disabled.
