R3 Series Overview

AdauraTech Helps Ensure Wireless Products Actually Work in the Real World with New RF Attenuators

The AD-USB4AR3 is AdauraTech’s latest design in the AD-USB series of programmable RF attenuators. Combining all the best features of the previous models, the R3 is the new series flag ship. With a completely custom machine aluminum enclosure, the R3 boasts 95dB of attenuation with over 100dB of chain-to-chain isolation. The addition of Ethernet allows EASY implementation into the most modern of test setups by allowing network control via HTTP web interface or direct Telnet while the USB port powers the device and allows for serial communication.

Key Features

  • 4 Channels in one compact housing
  • Total of 95dB of attenuation in 0.25dB steps
  • >100dB of interchain isolation
  • USB/COM and Ethernet Interface for wide-range compatibility
  • SMA Female connectors
  • A single USB connection for power and control of all 4 channels
  • HTTP RESTful API Support 

Serial Over USB Communication

…allows extremely FAST integration into existing test setups. Using any common serial console program, simply connect to the device to send it commands.

The example to the left shows a ramping function being executed on the device using the common serial program PuTTY. The command controls all FOUR of the channels simultaneously. Two of the attenuator’s channels are “Ascending” in attenuation from 0 to 5dB. At the same time, the other two channels are “Descending” from 5dB to 0dB. This command is executed with 1dB step intervals and a dwell time of 25ms.

The AD-USB4AR3 is ideal for cellular, microwave radio, IoT, MU-MIMO, and WiFi MIMO engineering development and manufacturing test. Each unit offers 4 channels of 95dB of attenuations in 0.5dB increments. Accessories include manual, GUI, programming guide, program examples on USB flash drive, along with a 5' USB Type A to B Cable and 5' CAT6 Ethernet Cable. The unit is constructed in a robust compact housing with SMA female ports. Software drivers are not required for Linux machines. Simply connect to the unit like any serial device using common Linux tools such as Minicom.
