ANTENNA TRAINING SYSTEM Catalog Download The Antenna Training System is a stand alone, very versatile table top system requiring no other high frequency equipments. It is a very useful tool that provides hands-on experimentation and understanding of the principle and working of commonly used antennas in the UHF-VHF-MICROWAVE band and to plot their polar plots. It can be used by students of all level. The antennas are designed for use at higher frequencies making them handy and smaller in size for better understanding. This system allows students to do analysis of radiation pattern, phenomenon of polarization, antenna parameters, antenna resonance, antenna reciprocity, ground reflection and hence to do the comparison of different types of antennas. Each kit includes Synthesized Digital RF Transmitter, Synthesized Digital RF Receiver, different types of Antennas and all the necessary cables and accessories. An exhaustive manual has been provided with the system covering all the experiments along with antenna theory and a set of polar graph paper for antenna radiation characteristics and all the other relevant documents. Antenna Training System has four different systems. ATS-3001 is a fixed frequency Antenna Training System. This trainer works at 610 MHz frequency. ATS-3002 is a basic Antenna Training System. This trainer provides antenna analysis at 100-850 MHz frequency range. ATS-3003 is a advanced Antenna Training System with software interface on PC. This trainer provides 86-860 MHz frequency range antenna analysis with Polar Plot software on PC. A stepper motor controller is provided to rotate receiving antenna circularly. ATS-3004 is a advanced Antenna Training System. This antenna trainer covers frequency range from 5MHz to 2GHz and also provides Polar Plot software on PC. A stepper motor controller is provided to rotate receiving antenna circularly. FEATURES: • Tabletop Stand-alone system requiring no other HF Equipment. • Different types of adjustable antennas. • Foldable antennas that fit into a tray system. • User selected transmitter and receiver frequencies and adjustable antenna lengths to cover a wide frequency range for variety of    experiments. • PLL stabilized antenna transmitter and receiver operation for testing and modeling of antennas. • Memories – in transmitter and receiver for storing various frequencies for antenna bandwidth measurements. • Memories in stepper controller for storing various angular positions for radiation pattern. • Stepper motor controlled Antenna positioning tripod with polarization facility for accurate, repeatable measurements. • User selectable steps to rotate either receiving or transmitting antenna with auto mode for plotting radiation pattern and easy PC    connectivity. • Antenna Polar plotting software for antenna analysis with side lobe level and its angular position, Directive gain, Front to back ratio,    Polar & Cartesian plot in Linear or log scale to the accuracy of 1 with printing and file saving facility, cursor measurements,    smoothing, rescaling, front and back reading trimming, de-spiking, pattern overlay, input calibration, data logging plus numerous    other features. • Antenna Beam width (3dB & 10dB).
