Don't settle for stability issues. AdauraTech's superior and highly-optimized software allows our devices to be relied upon in any long term testing.


We love our products, and we know you will too. We want you to be successful with your device no matter where you are, so we offer our customers full support as fast as we are able.


HTTP Webpage GUI 

The R3 series can be easily controlled across a network via an HTTP GUI. No need to install any applications. Simply load up a web browser and begin sending the device commands immediately.


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  R3 is ideal for cellular, microwave radio, IoT, MU-MIMO, and WiFi MIMO engineering development and manufacturing test. Each unit offers up to 4 channels of attenuations in as low as  0.25dB 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.


Quickly locate a device 

Stacking multiple units? Not a problem! Physically locate any device by sending the locate command to any unit based on its serial number.

This will blink the power LED on that unit for 10 seconds.
