AdauraTech AD-USB4AR2 programmable attenuators feature a unique design that provides 4 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.
- 4 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 4 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-USB42AR2 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-USB4AR2 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-USB4AR2 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 4 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.
