天線分析儀 ANTENNA ANALYZER An antena analyzer ' (also known as a noise bridge, RX bridge, SWR analyzer, or RF analyzer) is a device used for measuring the input impedance of antenna systems in radio electronics applications. MODEL: SA160 SA250 SA350 MINI1300 Read More FREQUENCY COUNTER A frequency counter is an electronic instrument, or component of one, that is used for measuring frequency. Frequency counters usually measure the number of cycles of oscillation, or pulses per second in a periodic electronic signal. Such an instrument is sometimes referred to as a cymometer. Model: SF401 SF103 Read More FIELD STRENGTH METER Field strength meter is actually a simple receiver. The RF signal is detected and fed to a microammeter, which is scaled in %. The frequency range of the tuner is usually within the terrestrial broadcasting bands. Model: SS10 SS11 Read More REPEATER CONTROLLER A repeater is an automatic radio-relay station, usually located on a mountain top, tall building, or radio tower. It allows communication between two or more bases, mobile or portable stations that are unable to communicate directly with each other due to distance or obstructions between them. Model: SR112 SR328 SR628 SR629 Read More V.S.W.R. POWER METER The standing wave ratio meter, SWR meter, ISWR meter (current "I" SWR), or VSWR meter (voltage SWR) measures the standing wave ratio (SWR) in a transmission line.[a] The meter indirectly measures the degree of mismatch between a transmission line and its load (usually an antenna). Electronics technicians use it to adjust radio transmitters and their antennas and feedlines to be impedance matched so they work together properly, and evaluate the effectiveness of other impedance matching efforts.
