D1-29 step attenuation measuring instrument

The attenuator is designed for reproduction of difference attenuation of electromagnetic oscillations with high accuracy in the frequency range from 0 to 150 MHz in steps of 10 dB.The main field of application of the attenuator is verification of measuring instruments.D1-29 is a step attenuator with the range of attenuation variation from 0 to 110 dB with 10 dB step, operating in the frequency range from 0 to 150 MHz.The device consists of a housing with attenuation cells and a switch with a counting device. In the housing there are coaxial input and output connectors, as well as additional connectors "40 dB" and "80 dB", necessary for verification of the device.
