Using Calibration to Optimize Performance in Crucial Measurements
Vaunix Technology Corp. (www.vaunix.com), a manufacturer of Lab Brick USB powered test equipment, has added an attenuation profile feature to the LDA series attenuators. The attenuation profile is user programmable with the capability to simulate various real-world fading conditions.
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.
Lab Brick Digital Attenuators are ideal for engineering and production test laboratories as well as integration into hig
h 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.
