The LDA-602Q from Vaunix is a 4-Channel Digital Attenuator that operates from 200 to 6000 MHz. This 50 Ohm bidirectional RF step attenuator has a programmable attenuation of up to 120 dB with a step size of 0.1 dB. This unit connects to a USB port for control and power and requires no additional DC supply voltage. It is available in a rugged aluminum enclosure that measures 3.86 x 2.52 x 1.35 in. and weighs 0.23 kg and is ideal for automatic-test-equipment (ATE) systems, Single Input Multiple Output (SIMO) communication systems such as WiMAX, 3G and LTE, wireless fading simulation, engineering and production test laboratories. 

It is easily programmable for fixed attenuation or swept attenuation ramps directly from the included GUI. A Lab Brick Digital Attenuator API DLL and LabVIEW-compatible drivers are also available for custom programming applications. Each device comes with a USB flash drive containing the GUI software and digital version of the programming guide, along with a 6-ft. USB cable. The Lab Brick Digital Attenuator GUI is compatible with Microsoft Windows & standard operating systems for personal computers, including Windows 2000, Windows XP, Windows Vista, and Windows 7.
