[[NeoScan]]® real-time field measurement and scanning system is a turnkey, electric or magnetic field probe and measurement system. It can be configured as a near-field scanning system for mapping aperture-level field distributions with minimal invasiveness to the device or system under test. Or it can be used as a real-time field probe system for sensing or detecting electric and magnetic fields in a variety of media.

<p>[[Image:icon_OBM.png|thumb|right|]] 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_small.png]] as shown in Figure 2.7. The program will start running as shown in Figure 2.8.</p>

During the scan or optimization process, the probe will be mounted on a plastic probe fixtures. The plastic probe fixtures has been mounted on translation stage by a single cap screw and holds the probe (Figure 2.10). The probe is positioned inside the gap located on probe holder and is secured by a cap which is fastened by screws as shown in Figure 2.11.

<p>To avoid bending the soft plastic shield of the fiber, pass the fiber through the top of the probe fixture using regular (Scotch) adhesive tapes as shown in Figure 2.13.</p>
<p>Important: When pulling out the probe from the hole, make sure the probe is positioned vertically and the probe tip does not touch the edges of the hole.</p>

Two black markers on the tangential probe indicate the E-field sensitivity direction (probesâ polarization direction). They should be oriented along the electric field in order to detect the maximum signal, see Figure 2.14.
