The contact connector on the optical modulation analyzer is angled. If you are
using a patchcord with straight and angled connectors, make sure you connect
the angled connector to the optical modulation analyzer.
Connecting to the optical modulation analyzer with a straight connector will
damage it.
Before you connect any fiber-optic cable to the Optical Modulation Analyzer,
please ensure it has been properly cleaned.
Fiber-optic connectors are easily damaged when connected to dirty or damaged
cables and accessories. When you use improper cleaning and handling
techniques, you risk expensive instrument repairs, damaged cables, and
compromised measurements.
After the Optical Modulation Analyzer application running on the
UXR-Series oscilloscope has initialized it, the green LED above the laser
output indicates whether the laser is emitting radiation.
The laser is enabled and disabled by the software.
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 not lit.
