A user-friendly system needs to work exactly as per demand of the user, so SICO decided to design and develop a unique combination of Antennae hardware and computer software which has on-line radition pattern plotting features.

 
The constituents of the system are :

 

1. Microwave Source - VCO/Klystron/Gunn based

2. Transmitting Antenna

3. Receiving Antenna

4. Microprocessor Controlled Turn Table

5. PC-Turntable Interface Card with Radiation Ploting Software (SICO-SRPS-SE)

6. RF Cables and Accessories.

 

The User can select Antennae asper his application and practical requirement, among various types of microstrip and waveguide antennae available with us. E & H-plane radiation pattern for S,C,X,K,Ku,Ka or set of any other band antennae can be plotted using SICO-SRPS-SE and gain measurement can also be done.

 
SICO-SRPS-SE software is a single window GUI application having options to initialise the turn table, setup reference (maximum) power, plot radiation pattern and to save data (degree of rotation Vs Power in dB)of the plot into the computer. This data can be used to plot the pattern in cartesian coordinate system. The computer should have RS-232C port and MS Windows XP operationg system to run the software properly.
