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 rechargeable battery, which is charged via the 2.5 mm DC jack by a provided DC to AC adapter. The 2.5 mm 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. The small but powerful stepper motor is capable of changing the attenuation from 0 dB to 60 dB in around 5 seconds. The attenuator is packaged individually in a rugged equipment box with additional hardware and tools. Electrical Specifications: *This product is intended to be used in a controlled lab environment.

  • All data presented is collected from a sample lot. Actual data may vary unit to unit.
  • All calibration and testing are performed at +25 °C room temperature.
  • This product is intended to be used in a controlled lab environment. To ensure best possible accuracy and prevent unintended behavior, please operate the unit as close to +25 °C room temperature as possible.
  • The phase shift value does change while varying the attenuation.
  • AC-to-DC power adapter and USB Type B to Type A adapter cable are included.
  • When the DC power supply is unplugged, the internal battery only provides power to the necessary internal functions for manual mode operation. The battery does not provide power for programmable mode operation; the DC power supply must be always plugged in during programmable mode operation.
  • Internal battery requires about 5 hours to recharge fully.
  • Internal battery performance will degrade over time during normal usage and charging.
  • Eravant reserves the right to change the information presented without notice. CAUTION:
  • The adjustable knob should not be turned when the attenuator is powered and operating under programmable mode. In programmable mode, the stepper motor receives power from the DC power supply. Turning the adjustable knob while the stepper motor is powered can generate back-EMF, which can damage the motor and impair the function of the unit.
  • Exceeding absolute maximum ratings shown will damage the device.
  • Any foreign objects in the waveguide will cause performance degradation and may damage the device. When not in use, use dust covers on the waveguide ports to prevent the ingress of dust and particles into the waveguides.
