VS-AT PC Based Manual Antenna Kit 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 RS-232 interface. In this Receiving antenna is rotated manually from 0 to 360 degrees and accordingly receiving antennas signal strength can be monitored on the Receiver.
The system consists of a set of two tripods – one for mounting the transmitting antenna and another for mounting the receiving antenna, 22 Antennas, RF Transmitter/ Receiver, Antenna Plotting Software and relevant accessories/ cables.

DESCRIPTION

The relay is basically an electromechanical device which comprises one or more set of contacts, open or closed by an electromagnet. The basic structure of relay is in form of coil.

The relays is an important primary control element in a control system which is being controlled by an electrical signal gives advantage of cost reduction. These system deliberately introduced as on –off control. This set up is designed to study of such relay control system characteristics. The set up has simulated relay with simulated process. There are three continuously variable controls. One is AMPLITUDE, meant to control the reference single amplitude. Another two controls are related with relay controller.
