PC Based Motorized Antenna Trainer

PC Based Motorized Antenna Trainer has been designed to provide useful tools for hands on experimentation and teaching of various commonly used antennas in VHF-UHF-Microwave band in the laboratory for students of all levels. It can be used in stand-alone mode as well as be interfaced with a computer via USB interface. In this Receiving Antenna can be rotated from 0 to 360 Degrees automatically with the help of Stepper motor controller unit and accordingly Receiving Antennas Signal strength can be monitored. The system consists of a set of tripod for mounting the transmitting antenna and another stepper motor controlled antenna positioning pod for mounting the receiving antenna, 22Antennas, RF Transmitter, RF Receiver, Stepper Controller Unit, Antenna Plotting Software and relevant accessories/ cables. Network Analyser: RFTransmitter & Receiver: Frequency : 86 - 860 MHz PLL synthesized Step Size : 0.05, 0.1, 0.25, 0.5, 1, 10, 100 MHz Accuracy : 0.01% Display : 16X2 Backlit LCD Functions : Menu, Enter, Escape, Up & Down Memory Location : 1000 individual frequencies and level can be stored/recalled Output Impedance : 50 Ohms RF Level : 90 dBuVTypical Measurement : RF level in dBuV with 0.1dB resolution Dynamic Range : 60 dB Log Manual/ Auto Mode : Data logging for antenna gain & polar/cartesian plot USB interface : Easy connectivity to PC using polar pattern plotting software Power Supply : 230V @ 50 Hz Stepper Motor Controller Unit: Rotation : 0-360 Degrees with 1 Deg resolution Angular Steps : 1, 5, 10, 45 degrees Display : 16X2 Backlit LCD Functions : Menu, Enter, Escape, Up & Down Memory : 1000 memories for storing angular positions for quick recall Auto mode : Automatic Rotation with Interface to Receiver Mode : Clockwise/Anti Clockwise Rotation, Fast /Slow Speed
