CHINA Transmission Line and Antenna Analyzer - JX3621

Adopting new techniques like advanced radio frequency and microwave hybrid integration design, broadband and fundamental wave mixing, digital IF processing and intelligent power management, etc. JX3621 Portable Transmission Line and Antenna Analyzer has advantages of wide measuring frequency band, high measurement accuracy, small size, light weight and battery power and so on and can measure return loss, standing wave ratio (SWR), impedance, DTF (discontinuity point fixing), etc. network parameters, suitable for measurement of standing wave ratio of cable, antenna and transmission line, etc. in field, as well as measurement of reflection parameters of radio frequency and microwave parts in scientific research and teaching.


Main Features

ο Wide frequency range. JX3621 Portable Transmission Line and Antenna Analyzer has a frequency range of 1MHz~4GHz and JX3622 Portable Transmission Line and Antenna Analyzer has a frequency range of 50MHz~18GHz, meeting the measurement requirements of most communication and radar equipment.
ο High measuring speed. The top measuring speed as high as 1ms/point increases by 10 times compared with the last generation product, thus saving your measurement time.
ο Support extended memory. Internal memory enables storage of over 200 traces (that may be different depending on the number of measuring points); meanwhile the external USB memory is also supported to expand memory space.
ο Convenient connection with the computer. It is convenient to connect with the computer through USB interface to enable upload and download of traces in memory from computer.
ο Large-capacity battery may enable the unit to run for over 4 hours continuously.

οFrequency Domain Reflectometer (FDR)

Frequency Domain Reflectometer (FDR) is similar to Time Domain Reflectometer (TDR) in the name, and both are used for measurement of transmission line. TDR sends excitation signal of DC pulse which can be used to measure the On/Off and off position of a cable but is insensitive to RF problems that may result in fault and performance degradation of RF communication equipment. While FDR adopts sweep signal for measurement, by getting time domain specification through complex mathematical operation, it may detect sight performance degradation of RF in system so as to do timely maintenance, thereby saving high maintenance cost of damage due to delayed repair of RF cable.



Typical Applications

In the construction, line maintenance and emergency repair of communication and radar, etc. systems, JX3621 Portable Transmission Line and Antenna Analyzer can promptly measure the return lose, detect and accurately locate the fault point in cable link, and in the meanwhile the measuring curves also can be downloaded to PC by using the tool software accompanied the instrument, which is convenient for preparing report, filing and printing.
