AdauraTech AD-USB2AR2 Programmable Attenuator

BRL Test is your authorized AdauraTech distributor

AdauraTech AD-USB2AR2 programmable attenuators feature a unique design that provides 2 channels in one compact package.  Great engineering delivers exceptional chain-to-chain isolation, greater than 100dB.  Test a much wider range of wireless applications with improved results. Easy to use. Low pricing.

To build better products you need to test better upfront.  Compete to win.  AdauraTech's high performance RF testing equipment is a simple to use, accurate and affordable solution.  

  • 2 Channels in one compact housing
  • 100dB of chain-to-chain isolation
  • USB/COM Interface for wide-range compatibility
  • SMA Female connectors
  • A single USB connection for power and control of  2 channels
  • Easy to use GUI providing fixed and ramp attenuation functions


?Many of the new products brought to market simply don?t perform as intended in the real world, all because they weren?t tested properly or ? sometimes ? at all,? said Blaise Yen, CEO of AdauraTech. ?There?s a simple reason for this: RF testing has traditionally been far too expensive, and way too complex. AdauraTech?s sole mission is to remove those barriers to proper wireless testing.?

AdauraTech's multiple channel attenuators offer a compact package with a single digital interface to control multiple channels. For many applications, 63dB of total attenuation and chain-to-chain isolation is sufficient to provide excellent performance ? but more advanced applications require even greater capabilities. AdauraTech?s AD-USB2AR2 provides greater than 100dB of chain-to-chain isolation with a patent pending new design, which significantly suppresses adjacent RF leakage levels. All of this is done with a design that keeps the cost down, and is paired with AdauraTech?s software for ease of use.

Testimonial: ?AdauraTech provides Quantenna with reliable, cost-effective solutions for our ever-expanding RF test requirements in both our laboratory and factory environments,? said Ray Ho, Engineering Manager at Quantenna. ?In our testing, the new AD-USB2AR2 attenuators have extremely consistent performance from channel to channel, and the reliability is exceptional.?
  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 both 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-USB2AR2 is  ideal for cellular, microwave radio, IoT, MU-MIMO, and WiFi MIMO engineering  development and manufacturing test. This device offers high input and accurate  step size. Each unit offers 2 channels of 63dB 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. 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.
