Vaunix LDA series Lab Brick RF and Microwave USB Programmable Digital Attenuators include 50 Ohm and 75 Ohm bi-directional RF step attenuators with calibrated operation up to 20 GHz. These low cost, portable, USB powered, hand-held wireless test devices are ideal for engineering and production test laboratories, field testing, and integration into high speed automatic-test- equipment (ATE) systems. They’ve been proven effective in the rapid and efficient development of wireless fading simulators for Multiple Input Multiple Output (MIMO), and Single Input Multiple Output (SIMO) wireless communication systems, such as WiMAX, 3G, 4G, and LTE. They’re also useful by wireless test engineers exploring next-generation 5G wireless systems.

LDA Series Lab Brick RF and Microwave USB Programmable Digital Attenuators are designed with advanced solid-state attenuator technology for excellent repeatability of attenuation values. These USB powered and controlled, hand-held wireless test devices require no additional DC supply voltage. They’re portable and are easily programmable for fixed attenuation or swept attenuation ramps directly from the included Microsoft Windows compatible GUI.
Dual port Lab Bricks are housed in rugged aluminum enclosures, some measuring 3.86 x 2.52 x 1.35 in. (98 x 54 x 34 mm) and weighing just 0.5 lb. (0.23 kg), and others measuring 4” x 2.5” x 0.95” (101.6 x 63.5 x 23.9 mm) and weighing 0.6 lbs (0.27 Kg). (See each model’s detail page for mechanical specifications). 4 port Lab Bricks measure 7.3” x 2.5” x 0.95” (185.4 x 63.5 x 24.1 mm) and weigh 0.9 lbs (0.41 Kg). All Lab Brick LDA Digital Attenuators are RoHS compliant.
Each Lab Brick attenuator comes with a USB flash drive containing the GUI software, Microsoft Windows SDK, Linux SDK, LabVIEW driver, a digital version of the programming guide, and a 6- ft. USB cable. Optional length cables, battery packs, and ruggedized USB hubs are available separately. All Lab Brick products come with Vaunix’s committed customer support.
RF and Microwave USB Programmable Digital Attenuators
This brief details the critical aspects of handover/handoff testing, and how recent technological advances have dramatically increased the complexity of such testing.
As instruments, rather than components like attenuators and phase shifters, signal generators are more complicated to set up. But our goal has been to make the Lab Brick LSG and LMS Series instruments portable and easy-to-use, while remaining extremely capable.
