1.Portable 1-port vector network analyzer GS320 for measuring matching characteristics of passive and active radio equipment (antennas, cables, filters, attenuators, amplifiers, etc.). . The device allows you to measure parameters such as complex reflection coefficients, standing wave ratio (VS WR), impedance, conductance, amplitude, phase, loss and fault distance in cables. 2.The unit is intended for amateur radio use as it is not a professional measuring inst ent. The presence of a built-in battery allows you to make measurements in laboratory and external conditions.
