Vaunix LDA-102E Overview

The LDA series of Lab Brick® Digital RF Attenuators includes50 Ohm and 75 Ohm RF step attenuators with calibrated operation up to 6 GHz.These units connect to a USB port for control and power and require no additionalDC supply voltage. They are easily programmable for fixed attenuation or sweptattenuation ramps directly from the included GUI. Lab Brick Digital AttenuatorAPI DLL and LabVIEW-compatible drivers are also available for customprogramming applications.

The Lab Brick Digital Attenuators are ideal for engineeringand production test laboratories as well as integration into high speedautomatic-test-equipment (ATE) systems. They can also be used in development oflow-cost fading simulators for Multiple Input Multiple Output (MIMO) and SingleInput Multiple Output (SIMO) communication systems such as WiMAX, 3G and LTE.They are based on GaAs monolithic-microwave-integrated-circuit (MMIC)attenuator technology for excellent repeatability of attenuation values.

Each device comes with a USB flash drive containing the GUIsoftware and digital version of the programming guide, along with a 6-ft. USBcable. The Lab Brick Digital RF Attenuator GUI is compatible with MicrosoftWindows™ standard operating systems for personal computers, including Windows2000, Windows XP, Windows Vista, and Windows 7. They are housed in ruggedaluminum enclosures, each measuring 3.86 x 2.52 x 1.35 in. (98 x 54 x 34 mm)and weigh just 0.5 lb. (0.23 kg). All Lab Brick LDA Digital Attenuators areROHS compliant.
