The LDA Series of Lab Brick Digital Attenuator series are USB attenuators that operate from DC to 6 GHz (available in multiple frequency configurations). They have an attenuation range of 120 dB with a step size of 0.5 dB, insertion loss of 5.5 dB and can handle up to 2 watts of input power. The attenuators are powered by a USB slot and do not require an additional DC supply voltage. They can easily be programed 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 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.
