High resolution USB programmable digital attenuator offers affordability and reliability

Vaunix Technology Corporation has released their new Digital Attenuator, the LDA-906V. The Lab Brick LDA series of Digital Attenuators offer affordability, functionality, reliability and simplicity to the microwave test bench. Capable of bidirectional fixed attenuation, swept attenuation ramps, and fading profiles, the device is a highly accurate 50Ohm step attenuator. It provides calibrated attenuation from 200MHz to 6000MHz with an impressive step size of 0.1dB and typical accuracy <0.2 dB over 90dB of control range. The device is ideal for testing WiMAX, 3G, 4G, 5G, LTE, DVB, and Microwave Radio Fading Simulators. The unit’s power and control connection is from a standard USB type-B female. Two counter-bore holes are providing for efficient mounting and placement. The one-channel digital attenuator is designed to operate reliably from -30C +70C.
