=== Installing the [[NeoScan]] System ===
[[Image:neoscanfig_2_1.png|thumb|center|650px|<i><b>Figure 2.1</b>: Installing NeoScan control computer.</i>]] [[NeoScan]] optical mainframe is enclosed in a 4U case with dimensions of 24”(H) x 17”(L) x 13” (W) (61cm x 43cm x 33cm). The instrument weighs 60 pounds (27kg) and contains the entire optical system, control systems, and power conditioning circuits required for electric field measurements. It is packaged in foam. Open the cardboard box and remove the layers of foam. Care must be taken to ensure the optical connectors, the SMA connectors, and the USB connectors on the rear panel are not damaged. Remove the fiber port protection caps and keep safe for reuse when repacking the instrument. The instrument box should contain the corresponding power cord, cables and etc.
Unpack the control computer (surface) and the computer holder. Attach the computer holder to the [[NeoScan]] front panel with the screws. Pull up the Holder Lock part on the top left. Place the control computer inside the computer holder. Pull down the Holder Lock part and lock it (Figure 2.1)

=== Installing [[NeoScan]] Translation Stage ===
[[Image:neoscanfig_2_2.png|thumb|center|650px|<i><b>Figure 2.2</b>: Installing NeoScan Translation Stage.</i>]] Unpack the [[NeoScan]] translation stage components. To install (see Appendix A-l):
<ul>
<lo>
<li>
Place the Y Linear Translation Stage on a stable flat table, preferably an optical table.
</loli><loli>
Mount the X Linear Translation Stage on the Y Linear Translation Stage using four screws as shown by red screws in Figure 2.2.
</loli><loli>
Mount the Plate on the X Linear Translation Stage. Fasten its four edges with screws as indicated by green arrows in Figure 2.2.
</loli><loli>
Place the X, Y, and Z Miniature Translation Stages on the front edge of the Optical Plate and fasten its four edges with screws as indicated by arrows in Figure 2.2.
</loli><loli>
Attach the Plastic Probe Fixture to the XYZ Miniature Translation Stage.
</loli>
</ul>

=== Unpacking the EO Probes ===
To unpack, open the box top. Remove the visible bubble wrap and remove the entire foam structure from the box. Cut the tape holding the foam structure halves together and remove the top. Remove any bubble wrap in the foam structure. Remove the cardboard covering the probe tip and any small pieces of foam holding the EO Probe down in the foam.

</center>
To remove a probe and the fiber from the box:
<lo>
<li>
Carefully press the both sides of the foam near the probe head, carefully un-wedge the probe from its slot, and then lift the probe. Figure 2.4 shows a picture how to remove a probe.
</li><li>
Carefully remove the probe from the foam, making sure to grasp the probe glass tube and not the probe tip, as this may damage the EO probe.
</li><li>
While holding the probe from its glass tube and keep the fiber sheath in your hand, avoid stretching the white plastic shield part of the fiber. Do not pull the plastic shield part hard.
</li>
</ul>
=== Handling the Probes and the Fibers ===
[[Image:neoscanfig_2_5.png|thumb|right|500px|<i><b>Figure 2.5</b>: Cleaning a connector end face using a dry cleaning cloth reel-based cassette cleaner.</i>]] The Probes and the fibers are made of a very pure, sensitive, and expensive materials. Treat them with care. Unwind a fiber gently and work out any tangles carefully.
<ul>
<li>
DO NOT pull hard the fiber.
</li>
<li>
DO NOT bend the fiber to a radius smaller than 4” (10 cm).
</li>
<li>
DO NOT strike the probe tip.
</li>
</ul>
Remove the protective cap on the optical fiber cable connector. Connectors should be cleaned before interconnection. Any dirt or contamination can damage the connector or degrade performance. In other words, fiber optic connectors should to be cleaned every time they are mated and unmated. Use a dry cleaning cloth (reel-based cassette cleaner) to remove dirt, dust, and oil from connector end faces (Figure 2.5). You can also carefully clean a dirty fiber connector with isopropyl alcohol (IPA) and then dry with FIS fiber optic cleaner.
The probe is coupled with a 10-meter-long PM fiber and connects to the optical mainframe with a FC/APC optical fiber connector. Remove the APC protection caps and keep safe for reuse when repacking the instrument. Gently clean and attach the appropriate fiber connectors to the correct fiber ports of the [[NeoScan]] system. There is a pre-aligned (slow or fast axis) adjustable key connectors for the PM axis alignment across a connection. Make sure the key is aligned in the slot properly before tightening, see Figure 2.6.

=== Quick Test of the [[NeoScan]] System ===
As a quick system test:
<lo>
<li>
Plug in the [[NeoScan]] optical mainframe power cord into an electrical receptacle and turn it on.
</li>
<li>
Connect control computer AC power adapter and turn on the control computer.
</li>
<li>
Connect USB multi-port Hub AC power adapter to the power.
</li>
<li>
Connect the [[NeoScan]] Optical Mainframe USB Interface Port on the rear panel to a port on the USB Hub, then connect the control computer USB Interface Port to another port on the USB Hub. The USB Hub is a plug and play device.
</li>
<li>
Attach the appropriate fiber connectors to the correct fiber ports of the [[NeoScan]] system (Probe 1, Probe 2, or Probe 3), see section 2.6.
</li><li> Open the [[NeoScan]] Optical Bench Manager program. The [[NeoScan]] Optical Bench Manager program is a Labview-Based System Operation which monitors the system status and the total return and polarization optical powers (see section 3.1 for more details). It is accessible through the desktop or Windows Explorer by double clicking on NeoScanOBM icon [[Image:icon_OBM.png]] as shown in Figure 2.7. The program will start running as shown in Figure 2.8. </li></lo> [[Image:neoscanfig_2_7.png|thumb|right|500px|<i><b>Figure 2.7</b>: NeoScan Program Group in or Windows Explorer.</i>]] When the program starts, the system should detect the total return power and polarization power and display their graphs over time and show their numerical values in mW, see Figure 2.8. The green “Probe Detected” indicator light will indicate that the probe is connected to the correct channel. Otherwise, if either the total return power or the polarization power is too low (less than 0.3 mW), the information panel will remind the users to correct the problem. This can be the case if the probe is not connected or is defective or there is a problem with the [[NeoScan]] system (Figure 2.9). Select the channel number you want to check using the dropdown list labeled “Select Channel.” <center>[[Image:neoscanfig_2_8.png|thumb|center|600px|<i><b>Figure 2.8</b>: The total return power and polarization power of delivered beam to optical probe.</i>]]<br>[[Image:neoscanfig_2_9.png|thumb|center|600px|<i><b>Figure 2.19</b>: NeoScan Optical Bench Manager indicating that the total return power is too low.</i>]]</center>
