Vaunix Technology announced the release of the company's new digital attenuator, LDA-906V. The Lab Brick LDA series of digital attenuators bring affordability, functionality, reliability and simplicity to the microwave test bench. The LDA-906V is well-suited for testing WiMAX, 3G, 4G, 5G, LTE, DVB and microwave radio fading simulators.
Capable of bidirectional fixed attenuation, swept attenuation ramps and fading profiles, the LDA-906V digital attenuator is a highly accurate 50 Ω step attenuator. It provides calibrated attenuation from 200 to 6000 MHz, with an impressive step size of only 0.1 dB and typical accuracy < 0.25 dB over a 90 dB control range.
The LDA-906V’s power and control are via a standard USB type-B female interface. Vaunix Lab Bricks use a native USB HID interface to avoid the difficulties inherent with older serial or IEEE-488 interfaces implemented over USB. So Lab Brick users get to work faster, without having to install kernel-level drivers, and Lab Brick devices can be easily used on any system that supports USB HID devices, including low cost embedded computers using Linux or similar operating systems.
The single-channel digital attenuator is designed to operate reliably from −30°C to +70°C. Two counter-bore holes are providing for efficient mounting and placement.
