S-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.
Key Specifications
S- 99R Receiver Synthesized
The receiver measures the incoming signal picked up by the receiving antenna. The input impedance is 50 ohms and the frequency range is 50 to 1300MHz. Frequency can be entered manually via the key board or via software. Wide dynamic range (100dB), 0.1dB resolution, 3dB typical level accuracy, 125KHz frequency resolution and narrow resolution bandwidth (300KHz typical) allow accurate spurious free measurements. The receiver also has a built-in positioner controller (via centronics port) and a serial port (RS232) for computer interface. The receiver connects to the transmitter generator via a co-ax cable for making tracking measurements.
S- 99V Transmitter Synthesized
The transmitter is a 50 ohms synthesized rf source to drive the transmitting antenna. Frequency can be keyed-in manually via the keypad or controlled by the receiver. The typical output is 115dBuV with a frequency resolution of 125KHz.
S- 99P Positioner Stepper
The stepper positioner rotates the Antenna in 1deg or 5deg steps. The stepper is controlled by the receiver via centronics interface to make synchronous measurements.
Antennas - 20nos. IIT Bombay designs
The antennas have been divided in three categories: Classical (7 antennas), Printed (7 antennas) and Microstrip (6 antennas). All the antennas are properly matched and have a VSWR<2 at the frequency of operation.
