1 Introduction __________________________________________________ Thank you for purchasing the RAMAC 2.5 GHz, the shielded high frequency antenna. Together with the RAMAC CUII control unit and the RAMAC Monitor for data acquisition you have the entire 2.5 GHz at hand, the high frequency concept, giving you a straightforward one-man operated GPR system for concrete, forensic and other high-resolution applications.
1.1 Unpacking and Inspection Great care should be taken when unpacking the equipment. Be sure to verify the contents shown on the packing list and inspect the equipment for any loose parts or other damage. All packing material should be preserved in the event that any damage occurred during shipping. Any claims for shipping damage should be filed to the carrier. Any claims for missing equipment or parts should be filed with Mala GeoScience. 1.
2 Hardware and Start Up __________________________________________________ 2.1 Hardware The 2.5 GHz is a one-piece radar antenna where the antenna elements are mounted in a small handheld, shielded box easily mounted on a small wheel carriage. See picture below. The RAMAC 2.5 GHz antenna communicates with the control unit CUII through a 3 m long data cable, giving you an easily and freely movable antenna. 2.2 Start up When initialising 2.
• • • • • • Make sure that the battery is fully charged for the control unit CUII (See Operating Manual CUII) and correctly mounted. This battery also supplies the 2.5 GHz antenna with power. Connect the CUII supporting system part to the CUII itself. Three short coaxial cables to the R, T and D connectors and the encoder cable to the CUII encoder connection. The T corresponds to transmitter, R to receiver and D to data. See picture below.
3 Using the RAMAC 2.5 GHz __________________________________________________ The 2.5 Ghz antenna is operated by 2 buttons on the shielded antenna box itself. You can easily create a new profile and start and stop the data collection. The 2.5 Ghz antenna can also be used together with an extension handle (see picture below), giving you access to the two different remote controls to manage the system.
The extension handle, with the remote control, are mounted on the wheel carriage and connected on the back-side of the 2.5 GHz antenna. See picture below. When the 2.5 GHz system is used together with the RAMAC XV11 Monitor, you have access o the fully integrated data collection, 2.5D analysis tool and Migration Wizard. See Manuals for the XV11 Monitor and Easy3D for further details.
