The LDA-133 Digital Attenuator from Vaunix is a bidirectional, 50 Ohm step attenuator that operates from 10 MHz to 13 GHz. It has a step size of 0.5 dB and 63 dB of control range with reliable and repeatable solid state digital attenuation. This lab brick can handle up to 2 Watts of input power. The device is compact enough to fit into a single rack unit for ATE applications such as; WiMAX, 3G, 4G, 5G, LTE, Microwave Radio and Satcom Fading Simulators.
This attenuator is easily programmable for fixed attenuation, swept attenuation ramps and fading profiles directly from the included Graphical User Interface (GUI). Users can also develop their own interface using Vaunix supplied LabVIEW drivers, Windows API DLL files, Linux drivers, Python examples and much more. The power and control connection is from a standard USB type-B female. This single channel digital attenuator is designed to operate reliably from -30 to +70 C.
