Installation for testing attenuators "D1-9".
Instruments for adjusting and controlling the PTA.Installation for checking attenuators "D1-9" has been produced since 1973 by the Gorky plant named after MV Frunze. The installation is designed for the establishment and periodic verification of microwave devices in laboratories or repair shops. It allows you to measure attenuation and calibrate individual attenuators, passive microwave elements and attenuators built into signal generators in the frequency range from 100 kHz to 17.44 GHz. Using the "D1-9" device, the attenuation of signals is measured from 0 to 100 dB at frequencies up to 1 GHz and from 0 to 80 dB at frequencies above 1 GHz. The unit is powered from an alternating current with a frequency of 50 Hz and a voltage of 220 V or a frequency of 400 Hz and a voltage of 115 V. Power consumption 135 VA. Dimensions of the device 320x480x475 mm. Weight 42.5 kg.
