ANTENNA TRAINING AND MEASURING SYSTEM MODEL 8092

8092 – shown with computer, not included

GENERAL DESCRIPTION
The Lab-Volt Antenna Training and Measuring System (ATMS), Model 8092, provides teachers and students with training materials for hands-on experimentation on antennas in the 1-GHz and 10-GHz bands. A convenient and powerful antenna measuring system, theATMS can also be utilized by design and research teams. The ATMS includes a set of 1-GHz antennas, a set of 10-GHz antennas, an RF Generator, a receiving system, and the Lab-Volt Data Acquisition and Management software for Antennas (LVDAM-ANT), a user-friendly software operating under the Microsoft® Windows™ environment. The receiving system consists of a rotating Antenna Positioner linked to a DataAcquisition Interface connected to the USB port of a Pentium-type personal computer (to be purchased separately). The ATMS is designed for low-power safe operation, both in the 1-GHz and 10-GHz bands, allowing measurement of antenna characteristics in these bands. The Data Acquisition Interface controls the Antenna Positioner and acquires the signal received from the antenna under test. TheLVDAM-ANT software provides a toolbox for controlling antenna rotation and data acquisition, and for displaying measured antenna characteristics in the E and H planes. Different forms of 2 D and 3 D representations are available from the results of the E- and H-plane pattern measurements as shown in Figures 1 to 5 on the next pages. The LVDAM-ANT software also includes algorithms for estimating thebeamwidth and directivity of antennas from measurements. The ATMS is a self-contained, stand-alone system that does not require other microwave equipment. However, optional antennas, a two element phasing kit, and a set of RCS demonstration accessories can be added to the ATMS in order to enhance the scope of experimentation on antennas and reflectors. These pieces of optional equipment are listedand described in the Optional Equipment and Optional Equipment Description sections of this data sheet. Furthermore, the ATMS is compatible with the Lab-Volt 10.5-GHz Microwave Technology Training System, Model 8090. The VSWR Meter and the Power Meter of the Lab-Volt

ANTENNA TRAINING AND MEASURING SYSTEM MODEL 8092
Microwave Technology Training System, along with microwave components such as the slotted line, the Gunn oscillator, attenuators, and couplers, can be put to use for various creative laboratory projects.

Figure 3. The acquired E- and H-plane patterns can be displayed simultaneously on atri-dimensional (3D) display (shown in figure: dipole antenna pattern).
