Packing Information
When unpacking your FPD310 FV, please check that the case contains the following items:
•1x FPD310 FV Detector (with markings “FPD310” / “400 1000nm”)
•1x Envelope with manual and test report
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 apply a light source to the photo diode.
•The FPD310 FV can be attenuated by 20dB operating the switch beneath the top with a small pen.
Maintaining the FPD310-FV
There are no serviceable parts in the FPD310 FV. 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 window of the
photo diode should only be cleaned using isopropyl alcohol and optical grade wipes.
If you suspect a problem with your FPD310 FV 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.
