2.2 CONNECTORS AND CONTROLS

The detector itself has two connectors on the opposite side of the optical input:

RF Ouput: SMA female connector Supply: multi-contacts Fischer receptacle

Connect the RF Output to a 50 Ω coupled measurement tool (e.g. oscilloscope, RF spectrum analyzer,…) via SMA cable.

Connect the low voltage cable of the provided power supply to the Supply receptacle and plug the power cord into the 100-230 V, 50-60 Hz outlet.

Each unit's housing features an M4 x 0.7 mounting hole (an adapter for imperial mounting is enclosed) that enables the amplified photodetector to be vertically post mounted (a 40 mm post is enclosed). For more information about the location of the mounting point, please see chapter 2.4 Technical Drawings.

3. INSTALLATION / OPERATION

Note: To prevent humidity condensation when the detector was stored or shipped at low temperatures, let the system packed for warm-up to room temperature.

The detector should always be mounted and secured for best operation.

 Unpack the detector unit. The mounting threat is metric (M4 x 0.7). For

your convenience an imperial adapter is included, if necessary. Mount it firmly.

 Connect the RF Output (SMA jack) to a suitable monitoring device, e.g.

oscilloscope or RF-spectrum-analyzer, with 50Ω impedance. Mount the device firmly in your setup. Please note that when the device is not mounted properly, involuntary displacements during operation might occur, leading to uncontrolled reflections from the device.

 Connect the low voltage plug of the provided power supply to the Supply

receptacle at the photo detector.

 Plug the power supply into 100 to 240 VAC, 50 to 60 Hz outlet.  Switch on the monitoring device, and apply a light source to the detector.

We recommend centering the incident light on the active area of the photodetector and not overfilling the detector area. Failing to do so may result in undesirable capacitance and resistance effects, arising from inhomogeneities at the edges of the active area of the detector, that distort the frequency response.

Page 14

4. MAINTENANCE

There are no serviceable parts in the photodetector. 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.

If necessary, for freespace version FPD photodetectors, the window of the photo diode should only be cleaned using isopropyl alcohol and optical grade wipes. For the NIR fiber coupled detectors, the FC/APC fiber connector may only be cleaned using appropriate fiber cleaning tools.

If you suspect a problem with your photo detector, please contact Menlo Systems’s technical support ([email protected]). They 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.

5. TROUBLESHOOTING

This section lists error conditions the user might troubleshoot, depending on the error’s root cause. If the information in this section cannot help, please contact Menlo Systems’ support. The contact information is at the end of this section.

Problem

Suggested Solution

There is no signal response.

 Verify that the power cord is connected and all

connections are secure.

 Verify the proper terminating resistor is

installed if using a voltage measurement device.

 Verify that the optical signal wavelength is

within the specified spectral response curve of the detector (see 2.3.1).

 Verify that the optical signal is aligned with the

active area of the detector. Sweep the area in the vicinity of the center.

 Adjust the oscilloscope to see if the signal is

off the visible portion of the oscilloscope.

Output Voltage will not increase.

 The photodetector might be saturated.

Reduce the incident power on the detector and check again.

C. CUSTOMER SERVICE

Your system is designed to be maintenance free. Opening the chassis of the system voids the warranty and exposes the user to

hazardous voltage.

C.1 FACTORY SERVICE & REPAIR

For factory service or repair please call the Menlo Systems’s customer service. Together with the product specialist they will determine if the equipment requires service, repair, calibration or replacement.

In case your system has to be returned to Menlo Systems for service or repair, we will provide an RMA number to you. For more information about the RMA procedure please read the online information at:

http://www.menlosystems.com/legals/service-plans-returns-rma/

C.2 ADDITIONAL SERVICE PLAN

Menlo Systems offers a Service Plan for all its products. The Service Plan includes onsite service for installation, on-site training and on-site repair service when this is technically feasible. We also support our customers during measurement campaigns. For more information please look at:

D. REGULATORY

As required by the WEEE (Waste Electrical and Electronic Equipment) Directive of the European Community and the corresponding national laws, Menlo Systems offers all end users in the EC the possibility to return "end of life" units without incurring disposal charges.

This offer is valid for Menlo Systems electrical and electronic equipment:

 Sold after August 13, 2005  Marked correspondingly with the crossed out "wheelie

bin" logo (see right)

 Sold to a company or institute within the EC  Currently owned by a company or institute within the EC  Still complete, not disassembled and not contaminated

As the WEEE directive applies to self-contained operational electrical and electronic products, this end-of-life take-back service does not refer to other Menlo Systems products, such as:

 OEM products, assemblies to be built into a unit by the user  Components  Mechanics and optics  Left over parts of units disassembled by the user (PCB's, housings etc.).

If you wish to return a Menlo Systems unit for waste recovery, please contact Menlo Systems for further information.

D.1 WASTE TREATMENT IS YOUR OWN RESPONSIBILITY

If you do not return an "end of life" unit to Menlo Systems, you must hand it to a company specialized in waste recovery. Do not dispose of the unit in a litter bin or at a public waste disposal site.

D.2 ECOLOGICAL BACKGROUND

It is well known that WEEE pollutes the environment by releasing toxic products during decomposition. The aim of the European RoHS directive is to reduce the content of toxic substances in electronic products in the future. The intent of the WEEE directive is to enforce the recycling of WEEE. A controlled recycling of end of live products will thereby avoid negative impacts on the environment.
