We are offering the VSWR sensor (measuring bridge(MB1)) and detector head (DH1), which are used in a set with measuring units (sweep frequency generator (SFG) and indicator unit (Я2Р-70) of P2-102 device.
Designation of P2-102 device are: panoramic displaying on the indicator and measurement of VSWR frequency characteristics and attenuation of elements of the coaxial tract. It is used in laboratory and enterprises bay at measurement and adjustment of VSWR parameters and attenuation of various microwave devices.
VSWR sensor is a measuring bridge (MB1),which forming signal proportional to reflection coefficient of the measured device in cross-section of a measuring connector at the expense of comparison of a reflected signal from internal reference loading with a signal, reflected from the measured device. The formed signal of unbalance is detected on the built — in detector and transferred in the measuring block.
It is 6dB resistance divider formed by three resistors; resistance of each is equal to a wave impendence of a coaxial line (50 Ohm).

Detector head (DH1) it intended for formation of low-frequency signals proportional to the power level of the microwave signals.
It is used for measurement of the module of transmission coefficient , amplification, attenuation, and for power measurement. Due to using of special designs (with the built — in amplifier with frequency F0=100 kHz) and resent element base the detector head has a bandwidth of frequencies and measured powers, small irregularity amplitude-frequency characteristics, low value of VSWR input.
