Antenna TrainerS-99 antenna trainer has been designed for teaching and demonstrating the commonly used antenna configurations at all levels of study. Practical verification of theoretical concepts is easily possible, because accurate, automatic and repeatable measurements of polar plots (involving 360/72 measurements) can be completed in 3 to 5 minutes. S-99 antenna trainer comprises of two towers for mounting the transmitting and receiving antenna, synthesized receiver, synthesized rf source with tracking facility and accessories like 20 antennas, antenna stepper positioner, directional coupler, etc. All the antennas are matched for a typical VSWR<2 and have been designed by Prof Girish Kumar, Elect Engg Dept, IIT Bombay, India. S- 99 antenna trainer works in stand alone mode as well as in conjunction with a PC. Polar plots of the antenna can be printed directly on an epson printer. STS-3006 antenna analysis software greatly enhances the understanding of electromagnetic concepts and measurement capability. The whole system can be easily accommodated on a standard laboratory bench. Distance between transmitting and receiving antennas is typically 3 to 6 meters for use within laboratories. However, due to the high sensitivity and wide dynamic range of the receiver the distance can be increased manifold. Experiment & Study Areas - Polar Plots

Transmission Line TrainerS-18 transmission line trainer has been designed for teaching and measuring the various parameters associated with transmission lines. Students can experiment, measure and understand the various abstractions like; characteristic impedance, standing wave pattern, VSWR, R+jX, impedance variation along mismatched line, smith chart, impedance matching, insertion loss, forward & reverse power and s-parameters(optional). students can also experiment with principles of time domain reflectometry; study pulse response to short, open, termination in Zo, velocity factor, fault location, etc on any general purpose laboratory oscilloscope - above 50MHz preferred. S-18 transmission line trainer is self contained and requires no other expensive RF measuring equipment. It comprises of a motorised 50ohm slotted line with voltage & current pickups, 1.3GHz synthesized receiver with built-in tracking RF source and TDR pulse output, directional coupler, dual slug tuner, various terminations, adapters and cables. S-18 transmission line trainer works in stand alone mode as well as in conjunction with a PC. Auto measurements can be made at 800MHz and the SWR printed directly via centronics on an epson lx800 or compatible printer. STS-3033 windows software greatly enhances the understanding of the transmission line theory. Experiment & Study Areas - Standing wave patterns upto four patterns at a time.
- Complex impedance measure R+jX.
- SMITH chart auto and manual.
- Study relationship of VSWR.
shift in minima, reflection co-eff for - Case 1: Matched Line
- Case 2: Open-Circuited Line
- Case 3: Short-Circuited Line
- Case 4: Inductive (nonresistive) Load
