[[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.

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 (probes’ polarization direction). They should be oriented along the electric field in order to detect the maximum signal, see Figure 2.14.
