“We were able to get attenuators working quickly and they’re absolutely great! The virtual serial interface is really simple and easy and the performance is excellent. Having the power derived off the USB makes it so clean to integrate into our test setup too. You make a great RF attenuator that has made doing my project so much easier!”

Why is the R3 a superior RF attenuator?
Why is the R3 a superior RF attenuator?
Cost Effective
The AD-USB line of programmable RF attenuators provides high-performance at an unheard of price, allowing the expansion of test setups in laboratories and factories all over the world.
Technology
Utilizing cutting-edge components and designs, AdauraTech RF attenuators can deliver stable and precise attenuation for any test. Easy to use USB and Ethernet interfaces provides quick implementation into any setup.
Reliable
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.
Supported
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.
Reliable when testing is critical
The AD-USB platform’s rock solid stability is relied upon in the most critical testing environments worldwide.
Advanced Desktop Controls
The Windows desktop application allows intuitive and fast control of our entire range of USB devices. Simply plug the device in and start the application to begin testing!
Power Over Ethernet
Power over Ethernet (PoE) is a technology that lets network cables carry electrical power. This feature allows simplicity in test setups as a single Ethernet cable can provide both power to the device as well as network control.

Hybrid HID & Serial USB Communication
Hybrid HID & Serial USB Communication
…allows extremely FAST integration into existing test setups. Why settle for one method when you can have the option of either? Our robust firmware provides the ability to connect and control with either USB Serial or USB HID.
- USB Serial enables the use of any common serial console program. Simply connect to the device to send it commands via RS232.
- USB HID provides another universal communication method as the device is recognized as a USB peripheral. Our convenient HID library can be easily implemented into test automation programs.
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.
