Antenna Measurement Training System Platform

System Introduction
As a carrier for transmitting or receiving electromagnetic waves in radio equipment, antennas play a very important role in engineering systems such as radio communications, broadcasting, television, radar, navigation, electronic countermeasures, and remote sensing.
This experimental system is mainly aimed at experimental courses in electronic information majors such as communication engineering, electromagnetic field and microwave technology, and antenna technology in colleges and universities. It is designed for experimental teaching, course design, graduation design, and secondary development.




System Features
1. The transmitting system features a built-in touchscreen LCD screen. Touch keys select the signal frequency band output and have a function to shut down the transmitting signal. The touch keys have power attenuation capabilities, allowing you to adjust the signal output power by touch. A reset function switches the transmitting power back to its initial value. The LCD screen displays the transmitting frequency and power level. The transmitting platform has a built-in power amplifier module to meet different testing requirements. The receiving system has a built-in touchscreen LCD screen that enables automated control of the antenna turntable's forward and reverse rotation, speed control, adjustable angle rotation, and sector sweep. The receiving system also has a built-in power test module that supports automatic and manual testing and drawing of directional patterns. It also has built-in USB and RS232 interfaces for connecting to a computer to display the antenna directional pattern and a printer to print the directional pattern.
2. The system includes software for automatically drawing antenna patterns, which are displayed directly on the LCD interface. It has the function of switching between straight coordinates and polar coordinates, and can measure the characteristics of various antennas. The test data can be saved or exported.
3. Antenna turntable: Equipped with an antenna pitch adjustment device, it can measure the vertical receiving radiation characteristics of the antenna; the vertical rotation platform can measure various antenna polarization patterns;
4. The built-in vector network analyzer supports simultaneous measurement of S11 and S21 in one scan, measurement of S parameters, voltage standing wave ratio, impedance, transmission line length, transmission line loss, Smith chart, and completes and quantitatively tests parameters such as the directivity pattern, antenna gain, antenna frequency response, antenna input impedance, and other parameters of different antennas, as well as extended experiments such as antenna matching network design.
