Vaunix LDA-602

Digital Attenuator - 6 – 6000 MHz
Contact us for pricing and availability.

The LDA series of Lab Brick® Digital Attenuators includes 50 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 additional DC supply voltage. They are easily programmable for fixed attenuation or swept attenuation ramps directly from the included GUI. Lab Brick Digital Attenuator API DLL and LabVIEW-compatible drivers are also available for custom programming applications.

The Lab Brick Digital Attenuators are ideal for engineering and production test laboratories as well as integration into high speed automatic-test-equipment (ATE) systems. They can also be used in development of low-cost fading simulators for Multiple Input Multiple Output (MIMO) and Single Input 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 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. They are housed in rugged aluminum 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 are ROHS compliant.
