  • Programmable/Direct Reading Attenuators

    ERAVANT

    Is a dual function direct reading and programmable rotary vane type attenuator for use in millimeterwave systems across the standard WR-03 frequency range of 220 to 330 GHz. The attenuator is an ideal piece of equipment in waveguide systems where a broad direct reading of attenuation is required. The default mode of operation is manual direct reading. In manual mode, the attenuation is adjustable with the large knob and the digital LCD screen displays the current attenuation value. The LCD screen is powered by an internal rechargable battery, which is charged via the 2.5mm DC jack by a provided DC to AC adapter. The 2.5mm DC jack also provides power to the stepper motor, encoder and internal microprocessor for the programmable mode function. The user can quickly switch to programmable mode by connecting the powered-up attenuator to a computer with the USB Type B port. In programmable mode, the attenuation is finely adjusted with a precision stepper motor by the internal microprocessor via user-entered serial port commands from the computer.
