OE695G Optical-to-Electrical Converter

Operation
Connecting the Unit to the Oscilloscope
To connect the optical to electrical converter to a Teledyne LeCroy
oscilloscope:
1.
Attach the OE695G 2.92mm connections to the oscilloscope 2.92mm
interface. Use a torque wrench to provide appropriate torque when
tightening.
2.
If connecting to a ProLink interface, first connect the LPA 2.92mm
ProLink to 2.92mm adapter to the oscilloscope, then connect the
OE695G to the adapter.
3.
Connect the OE695G LEMO connector to the power connection of the
oscilloscope 2.92mm interface or the LPA-2.92 adapter. Align the red dot
on the cable to the red mark on the connector.
4.
Verify the LEMO power connector is locked to the connection.
5.
Connect the other end of the SMA cable to the converter, if not already
connected. Use a torque wrench to ensure proper torque.
6.
Connect the other end of the LEMO power cable to the OE695G.
7.
To disconnect power, pull on the LEMO connector tip to release the lock
and pull out the LEMO connector.
Connecting the Unit to the Optical Fiber
A plastic cap covers the FC/PC input connector. Carefully remove this cover
and insert a fiber optic cable with a cladding dimension of 125 µm. The core
diameter should nominally be 62.5 µm. Other core diameters may be used
with the OE695G, but a smaller or larger diameter will alter the amount of
light falling on the photo-receiver and impact the gain accuracy of the
OE695G. Both multi-mode and single-mode fibers may be used with the
OE695G provided they are mechanically compatible.
Operation with a Teledyne LeCroy Oscilloscope
After the OE695G connectors are attached, the converter can be controlled
through the oscilloscope. Turning the VOLTS/DIV knob will control the
oscilloscope’s scale factor to give full dynamic range in µW/div.
