Packing Information
When unpacking your FPD510, please check that the case contains the following items:
1x FPD510 Detector (with markings “FPD510” / “850-1650nm”)
1x Envelope with test report and this manual
Setup and Operation
After unpacking, connect the power supply to the detector as depicted in the
following sketch; refer to technical drawings and labelling of the device to locate
the respective connectors:
Best performance of the detector can be achieved when using a linear regulated
power supply. Note that switched power supplies may introduce switching noise
that could potentially carry through to the output signal.
Connect Signal Out (SMA jack) to a suitable monitoring device, e.g. oscilloscope or RF-spectrum-
analyzer, with 50Ω impedance.
Mount the device firmly in your setup using the mounting holes (at least one of the two holes
through the device or M4-threaded hole at the side). Please note that when the device is not
mounted properly, involuntary displacements during operation might occur, leading to uncontrolled
reflections from the device.
Switch on the power supply and monitoring device, and connect the FC/APC connector to your light
source. Please note that only FC/APC connectors may be used for mating.
Maintaining the FPD510
There are no serviceable parts in the FPD510. The housing may be cleaned by wiping with a soft damp
cloth. Do not use any alcohol or organic solvent to clean the mechanical parts. The FC/APC fiber
connector may only be cleaned using appropriate cleaning tools.
If you suspect a problem with your FPD510 please contact Menlo Systems and technical support will be
happy to assist you. For service requests, please make sure to provide the serial number of your device.
For storage and shipping, please use the case your detector was shipped with.
