Enabling and disabling the laser output

Starting the LCA

Keysight N4376E Lightwave Component Analyzer Getting Started Guide
These result in frequency dependent interference effects (ripple), which
may significantly degrade the performance of the LCA. This may impact
user calibrations in OE and OO measurements. We recommend you use
the patchcords supplied to minimize the number of straight connections.
Using the patchcords also keeps service costs down, as the adaptor
patchcord can be exchanged easily.
Angled contact connectors have up to 30 dB higher return loss than
straight connectors, and we recommend them for best performance
results. With angled fiber endfaces, reflected light tends to reflect into the
cladding, reducing the amount of light that reflects back to the source.
You can switch the Laser on and off by pressing the button besides the
Optical Output.
After the LCA application running on the network analyzer has initialized it,
the green LED besides the laser output indicates whether the laser is
emitting radiation. If the Laser output is on, the green LED on the front
panel of the module is lit. If the Laser output is off, the green LED on the
front panel of the module is unlit.
This button overrides the internal laser ON/OFF settings. Pressing this
NOTE
button during a measurement will cause errors in the results.
1 If it is not already running, start the LCA server by pressing
or by clicking the LCA server icon on the desktop.
If the LCA server is running, but the function keys are not displayed,
press the [Macro/Local] Utility key until they appear.
2 Press
You can now proceed with setting up a measurement. For further
information on measurements, refer to the User's Guide.
