LDA-906V-8 Image

The LDA-906V-8 from Vaunix is a highly accurate, bidirectional, 8-Channel Digital Attenuator that operates from 0.2 to 6 GHz. It has an attenuation range of 90 dB with a step size of 0.1 dB and typical accuracy better than 0.25 dB. It can handle up to 26 dBm of input power.  This Digital Attenuator is a portable USB powered device that is sized to fit into a single rack unit for ATE applications. It can be used with WiMAX, 3G, 4G, 5G, LTE, DVB and microwave radio fading simulators as well as in engineering and production test labs.

This attenuator module has a native USB HID interface to avoid the difficulties inherent in using older serial or IEEE-488 interfaces implemented over USB. As a result, Lab Brick users can get to work faster without having to install kernel level drivers, and Lab Brick devices can be easily used on any system that supports USB HID devices, including low cost embedded computers using Linux or similar operating systems.

The attenuators are easily programmable for fixed attenuation, swept attenuation ramps and fading profiles directly from the included Graphical User Interface (GUI). Users can also develop their own interface, Vaunix supplied LabVIEW drivers, Windows API DLL files, Linux drivers, Python examples and much more.
