Product Description :
Antenna Training Lab ATS20 Model ATS20 Antenna Training Lab has been designed to provide useful tools for hands on experimentation and teaching of various commonly used antennas in VHFUHF- 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 RS232. The system consists of a set of two tripods – one for mounting the transmitting antenna and another stepper motor controlled antenna positioning tripod for mounting the receiving antenna, 30 different types of antennas, PLL synthesized Digital RF Transmitter, PLL synthesized Digital RF Receiver & Stepper Controller and all the necessary cables and accessories. Features: * 30 different types of adjustable Antennas like Log Spiral, Batwing, Stacked Yagi, Helix, Quad, Slot, Log periodic, Discone, Biconical, GPS Patch, Parabolic dish etc. are offered * User selected variable transmitter & receiver frequencies and adjustable antenna lengths to cover wide frequency range for variety of experiments * PLL stabilized antenna transmitter and receiver operating in the frequency range of 5-2000 MHz with 50 KHz step size for full range testing and modeling of antennas. * Rs232 interface with polar plotting software with log, linear cartesian and polar plots, Vi, Vr & VSWR plots, Multiple pattern overlay, Double cursor measurement, Zoom, Colour editing, 1000 location editor, Absolute/Relative measurement , 3dB/10dB beamwidth measurement Technical Specifications: PLL Synthesized Digital RF Transmitter Frequency range: 5-2000 MHz PLL synthesized in 3 ranges Step size : 0.05, 0.1, 0.25,0.5, 1 & 10 MHz Accuracy : 0.01% Display : 16X2 Backlit LCD Controls : Menu, Enter, Escape, Up & Down buttons.
