We measure standing wave ratio for you - SWR(=VSWR)=?

SWR - what is it and why is it so important?
What does the abbreviation in the title stand for? And why is for M2M technology so important? SWR is a standing wave ratio (VSWR - voltage standing wave ratio). The names of the winning number parameter is ultimately one of the important indicators of the effectiveness of the entire wireless broadcasting equipment. In fact, it is considered that all the RF components such as transmitter output, RF coaxial cable and antenna must be adapted to each impedance ... and the impedance of a given frequency must be identical. If these preconditions meet, then the SWR (= WSVR) is equal to 1.

How do we measure SWR (SWR)?
Measurement of SWR requires some basic theoretical knowledge, quality measuring equipment and finally is very important calibration of the whole measuring system. In SECTRON we measure SWR using handheld cable and antenna tester Agilent N9330A, which operates in the range from 25 MHz to 4 GHz. This device allows to measure parameters in the frequency domain such as reverse attenuation, standing wave ratio and attenuation of the cable. It also measures the dependence of reverse attenuation or  standing wave ratio on the cable length (the distance-to-fault). For the calibration we use electronic calibration kit.

Measure the SWR in SECTRON!
The SWR measurement is suitable for cable adaptors or extension cable in case you need to check the VSWR for the desired frequency range, for example, as you select the appropriate type of cable or connectors. The final measurement result depends on the quality of the coaxial cable connector assembly at the same time the quality of the connectors on the cable.
Outupu of measurement is very clear SWR grap. Frequency measurement range is set based on customer requirements, or we can recommend them. Measured results are available in printed form or in electronic form as .jpg or .pdf.
