Product Review: AV36210 / 36211 handheld antenna and transmission line tester uses advanced RF and microwave design hybrid integration technology, broadband fundamental mixing technology, the digital IF processing technology, intelligent power management technology and other new technologies, with a measurement frequency band width, measure high precision, small size, light weight, battery-powered, etc., to measure return loss, VSWR, impedance, VSWR DTF (discontinuity point positioning) and other network parameters, for live cables, antennas, transmission lines, and the ratio testing, and research and teaching for RF, microwave reflective component parameter test. Main features: ◆ band width. AV36210 handheld antenna and transmission line tester frequency range of 1MHz ~ 4GHz, AV36211 handheld antenna and transmission line tester frequency range of 50MHz ~ 18GHz, to adapt to the needs of most test communications, radar. ◆ fast measurement speed. Up to 1ms / point measurement speed than the previous generation products increased more than 10 times, save your test time. ◆ expand storage support. The machine supports trace memory storage than 200 (according to different measuring points are different), also supports external USB memory, the number of extended storage. ◆ Convenient computer connection. Can be easily connected to a computer via USB interface to a computer for storage traces downloads and uploads. ◆ Large capacity battery. Can support more than four hours of continuous work. ● Frequency Domain Reflectometry (FDR) Frequency Domain Reflectometry (FDR) time domain reflectometry (TDR) and a very similar name, and are used to test the transmission line. TDR transmitter excitation signal is a DC pulse, it can test the off position and disconnect the cable for RF communications equipment can cause performance degradation and failure of RF insensitive. And FDR use sweep tested to obtain time-domain characteristics through complex mathematical measure subtle RF system performance degradation, timely maintenance, saving maintenance costs due to high RF cables are not damaged due to timely repair.
