Antenna Tester is a special instrument to test the matching and VSWR between base station antenna and feeder , also known as VSWR tester. It covers the VSWR testing, fault location, cable loss test function. It is mainly used for testing a variety of antenna feeder system for communication base station, including the cluster, GSM, CDMA, GPRS, WCDMA, CDMA2000, TD-SCDMA etc. Antenna Tester uses advanced radio frequency integrated circuits and digital circuit combined integrated design technology, the digital IF processing technology and other new technologies, with measurement speed, high accuracy, small size, light weight, etc., can test VSWR, Return loss, the characteristic impedance and the phase test, and exactly locate the fault.
Antenna system installation, commissioning and maintenance, handheld Antenna Tester can help users to quickly assess the state of the transmission line and antenna systems, to improve maintenance efficiency operation of the base station, to accelerate the process of installation and commissioning of new base stations. Meanwhile it can be used for reflection parameters test of components for the RF device in scientific research, teaching and production.
Ø VSWR and Return Loss
It provides a standard for VSWR and return loss testing capabilities, provides a guarantee for accurate testing Antenna System Index, provides important basis for the measurement of Antenna System.
Ø Cable Loss
Cable loss test can accurately complete the feeder transmission insertion loss test, and automatically gets the average loss results of feeder system based on test data.
DFT is an important means to troubleshoot the system fault location. Fault location measurement uses fast Fourier transform technology to change frequency domain data into time domain, to achieve precise analysis of the distance.
Ø Single-port Calibration
Using open circuit, short circuit, load for calibration, to eliminate the source mismatch errors, directional error and receiver frequency response error, and then it can be accurately measured the vector.
