LDA-102N Image

The LDA-102N Lab Brick® Digital Attenuator is a 50 Ohm RF step attenuator with N Type Connectors that can be calibrated for operation up to 1 GHz. This unit connects to a USB port for control and power and requires no additional DC supply voltage. It is 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 LDA-102N Lab Brick Digital Attenuator is ideal for engineering and production test laboratories as well as integration into high speed automatic-test-equipment (ATE) systems. It 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. It is 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. It is 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.
