2 Safety Information
WARNING
Do not install or terminate fibers while a light source is active. Care
must be taken to ensure that the instrument has been turned OFF
before inspecting the end face(s) of the instrument, or any optical
patch cords connected to this instrument. Never look directly into a live
fiber and ensure that your eyes are protected at all times.
The use of controls, adjustments and procedures other than those
specified herein may result in exposure to hazardous situations or
impair the protection provided by this unit.
CAUTION
The DopplerPXIe modules are sensitive to electrostatic discharge (ESD).
Please be sure to store the modules that are not installed in protective
electrostatic packaging.
IMPORTANT
For electromagnetic compatibility, this instrument is a Class A product.
It is intended for use in an industrial environment. There may be
potential difficulties in ensuring electromagnetic compatibility in other
environments, due to conducted as well as radiated disturbances.
When you see the symbol on your unit, make sure that you refer
to the instructions provided in your user documentation. Ensure that
you understand and meet the required conditions before using your

3.2 Functional Diagram
Two lasers are connected to the Target Input port and Reference Input ports respectively. The
Target laser passes through a circulator and exits the Probe port. This beam will interact with the
DUT (target) and be reflected into the Probe Port.
The input into the probe port will pass through the circulator and be directed to the optical
attenuator and inline power meter.
The Reference laser passes though an optical attenuator and inline power meter.
The Reference laser and the Probe input are coupled to the Output port through a 10%:90% coupler
respectively.
Through this configuration, independent control of the Probe power and the Reference power is
achieved. The Power Meter is referenced to the output port, so it takes all internal losses of the
optical coupler into consideration when reporting the optical power of the probe and reference.

4 Connecting Optical Output
IMPORTANT
To ensure maximum power and to avoid erroneous readings always inspect
fiber ends and make sure that they are clean as explained below before
inserting them into the port. Coherent Solutions is not responsible for
damage or errors caused by bad fiber cleaning or handling.
CAUTION
The type of optical connectors on the DopplerPXIe module can be found
printed on the front plate of the module and in the separate Spec sheet
provided. Joining mismatched connectors will damage the ferrules.
4.1 Cleaning and Connecting Optical Fibers
To connect the fiber-optic cable to the port:
1. Inspect the fiber using a fiber inspection microscope. If the fiber is clean, proceed to connecting
it to the port. If the fiber is dirty, clean it as explained below.
2. Clean the fiber ends as follows:
2a. Gently wipe the fiber end with a lint-free swab dipped in isopropyl alcohol.
2b. Use compressed air to dry completely.
2c. Visually inspect the fiber end to ensure its cleanliness.
3. Carefully align the connector and port to prevent the fiber end from touching the outside of the
port or rubbing against other surfaces. If your connector features a key, ensure that it is fully
fitted into the port’s corresponding notch.
4. Push the connector in so that the fiber-optic cable is firmly in place, thus ensuring adequate
contact. If your connector features a screw sleeve, tighten the connector enough to firmly
maintain the fiber in place. Do not over tighten, as this will damage the fiber and the port.
Note: If your fiber-optic cable is not properly aligned and/or connected, you will notice heavy loss and
reflection.
Coherent Solutions uses good quality connectors in compliance with EIA-455-21A standards.
To keep connectors clean and in good condition, Coherent Solutions strongly recommends
inspecting them with a fiber inspection probe before connecting them. Failure to do so will result in
permanent damage to the connectors and degradation in measurements.

6 Handling the DopplerPXIe Module
6.1 DopplerPXIe Module Installation
WARNING
DO NOT attempt to remove or adjust any component of the PXIe chassis
while the power is on. Make sure you follow the correct procedures below
and power down the chassis first.
CAUTION
Do not remove the DopplerPXIe from the antistatic packaging until
instructed during the following installation procedure.
The DopplerPXIe is sensitive to ESD. Please be sure to wear a grounded
wrist strap at all times when handling the DopplerPXIe module to
prevent such damage.
Take care not to handle the connector on the DopplerPXIe module
once they are exposed as this may leave corrosive residue which can
damage the connector.
1. Shutdown the PXIe chassis.
2. If present, remove the current module or
blanking plate in the intended installation
slot.
3. Carefully remove the DopplerPXIe module
from the antistatic packaging bag it was
shipped in.
Retain the bag for storage of the
DopplerPXIe module.
4. Insert the DopplerPXIe module into the
desired slot.
Align the top and bottom lip of the
DopplerPXIe module with the chassis guide
rails. With a firm grip push the module into
the chassis.
PXIe Platform Photonic Doppler Velocimetry | DopplerPXIe
Coherent Solutions | 19
5. Push the module into the chassis until a
resistance is felt.
This is to confirm the header pins on the
back of the module are properly connected
to the chassis.
6. Secure the module into the chassis by
pulling up on the black locking clip.
A click should be heard when the locking
clip is properly engaged into the front
chassis rail.
Secure the fastening screw with a
screwdriver.
7. Perform a visual check to ensure no loose
items or tools have been left in the chassis
after installation.
Power on the PXIe chassis.

6.2 DopplerPXIe Module Uninstallation
IMPORTANT
After powering on the PXIe chassis, please wait at least 2 minutes before
attempting to communicate with the instrument. This will allow the chassis
enough time to finish boot procedures and initialize the communication
server.
1. Shutdown the PXIe chassis.
2. Unfasten the locking clip on the DopplerPXIe
module. Unscrew the fastening screw.
Pull out the module from the chassis while
firmly gripping the front plate edges of the
DopplerPXIe module. DO NOT PULL THE
MODULE OUT BY GRIPPING ANY OF THE
CONNECTORS.
3. Insert the DopplerPXIe module in the
antistatic bag it was shipped in. Store
appropriately.
4. Power on the PXIe chassis.

7 Programming Guide
Introduction
Remote communication with the CSLServer is achieved through the Standard Commands for
Programmable Instruments (SCPI). Support for VISA I/O API over TCP/IP is provided by the VXI-11
compliant CSLServer. With VISA communication drivers installed on the client, the implementation
of VISA programming within environments such as MATLAB becomes available. This guide provides
general information on the commands available to communicate with the CSLServer remotely using
the VISA I/O.
7.1 Programming Conventions
This section details the programming and measurement conventions to follow while executing the
commands for the CSLServer.
Table 1 - Valid Units and Data Formats
Argument
Data Format
<wsp>
Specifies whitespace character (0116 – 0916, 0B16 – 2016).
<value>
Is numerical data, an integer, a decimal, exponential (10e-9 or 5.8e6) or
string
[VALUE1|VALUE2]
This is a parameter choice. The ‘|’ separates the unique parameters
available, only one of the choices can be used.
In the example you can use the input parameter [VALUE1] or [VALUE2]
not both.
Some commands may have more than two choices available.
This parameter can be omitted where the command has a default defined
in the command description.
Index Addressing of Modules (slot, source) and VOA’s (channel)
When executing commands, it is almost always necessary to provide the index of a specific
DopplerPXIe module or an index of a specific attenuator.
For the commands that require index values:
[n]: is the slot (or source) index of the specific blade module, this is an integer, <1 to 18>
[m]: is the channel index of a specific attenuator, this is an integer, <1, 2 >.
Message Queues
Information is exchanged in the form of messages. These messages are held in input and output
queues.
The output queue stores responses to query commands. The CSLServer transmits any data in the
output queue when a read request is received. Unless explicitly specified otherwise in the command
description, all output response data is transmitted in ASCII format.
