Complex reflection and transmission coefficient measuring devices (vector network analyzers)

Automated measurement of transmitting and reflecting coefficients (S11 and S21 ) with digital readout of measurable values and reproduction of their frequency responses on the VNA display. The terminal-type devices, such as two-pole circuits, or open-end devices, such as four-pole circuits, can be used as the devices under tests. The VNA can be used both in laboratory and shop-floor conditions to measure S-parameters and adjust microwave devices. The VNA is based on the «client-server» technology using Ethernet interface, which allows integrating the analyze to computer-aided measuring systems and performing remote calibration. The VNA is designed for use in laboratory conditions to measure S-parameters and adjust microwave devices with a standard size of the waveguide circuit. The measuring system demonstrates its full performance in compliance with the standards as the operating mode set-up time of 15 minutes, is over. The continuous operation time is 16 hrs. ADVANTAGES: the system can be easily linked to peripherals using computer interfaces such as Ethernet and RS-232.
