GS-320 Hand vector network analyzer VNA (reflectometer) 23-6200 MHz is designed to measure the matching characteristics of passive and active radio devices (antennas, cables, filters, attenuators, amplifiers, etc.). GS-320 will be especially useful to companies working in of telecommunications, engaged in the installation and maintenance of antennas, in the amplification of cellular communication, etc. With it, service centers and repair crews can carry out RF analysis cable and antenna when carrying out commissioning or repair work. In addition, the device is ideal for workshops, radio amateurs, educational institutions and laboratories. For example, you can use the instrument to do the following: - To impedance matching using the chart - To measure the standing wave - To measure the attenuation in the cable - To measure the distance to fault or irregularity in the cable Material: Metal + Plastic colour: black Package Contents: 1 x 6G vector network analyzer 1 x USB Type-C data cable 1 x SOL calibration piece set 1 x N female to SMA male adapter 1 x Touch screen pen Only the above package content, other products are not included.
