The [[NeoScan]] real-time field measurement and scanning system consists of:
<ul><li>An optical mainframe with a touchscreen control computer that can be used for either real-time high power microwave measurement or E-field scanning as shown in Figure 1.5. Â The power switch on the back will turn the system and the laser on or off. It is recommended to turn the [[NeoScan]] system on at least 30 minutes before any operation for warm-up. A USB port is used to communicate with control computer. The âSignal Outâ channels can be used for real-time measurements. The RF signal can be displayed either on a high resolution oscilloscope or a spectrum analyzer. The channels can also be configured for near-field scanning measurement with a U-jumper SMA Cables. The scanning configuration can measure both amplitude and the phase of the signal with a Lock-in Amplifier. </li><li>
One normal probe and two tangential probes
</li>
<li>
One 2-axis translation stage with a stage controller for scanning operation (Figure 1.6)
</li>
<li>
One RF Lock-In Amplifier
</li>
<li>
One GPIB-USB cable for instrument control
</li>
<li>
One USB multi-port Hub for instrument control
</li>
<li>
The [[NeoScan]] system control software package
</li>
</ul>
Additional equipment needed to configure [[NeoScan]] as a field scanning system include:
</ul>
<li>
A signal generator to provide the local oscillator (LO) signal for [[NeoScan]]âs output mixer
</li>
<li>
A signal generator to provide a 100 MHz reference signal to lock-in amplifier
</li></ul>
==== The Front Panel of [[NeoScan]] Optical Mainframe ====
The rear panel is the interface to the instruments and provides complete access for external control, optical fiber excitation, and RF signal output (Figure 1.8). It contains:
<ul>
<li>
A USB interface port for computer control of the system
</li>
<li>
The power switch and red LED Power indicator for turning on or off the system
</li>
<li>
The AC power cord. The AC power requirement is 110V, 60Hz with a 250V 2A fuse
</li>
<li>
Three SMA connector for RF output (Signal Out)
</li>
<li>
Three fiber FC/APC connector (Probe)
</li>
<li>
SMA connectors for frequency scanning mixer includes: IF Out, LO In, and RF In
</li>
<li>
SMA connectors for IF Switch Out and IF Switch Ins
</li>
<li>
An electric fan
</li>
</ul>
