High Resolution USB Programmable Digital Attenuator Covers 200 to 6,000 MHz

Newburyport, MA – May 25, 2018 – Vaunix Technology Corporation, a manufacturer of programmable wireless network test devices, is pleased to announce the release of their new Digital Attenuator, LDA906V. The Lab Brick LDA series of Digital Attenuators bring affordability, functionality, reliability and simplicity to the microwave test bench.

Capable of bidirectional fixed attenuation, swept attenuation ramps, and fading profiles, The LDA-906V Digital Attenuator is a highly accurate 50 Ohm step attenuator. It provides calibrated attenuation from 200 to 6000 MHz with an impressive step size of 0.1 dB and typical accuracy <0.25 dB over 90 dB of control range. The LDA-906V is ideal for testing WiMAX, 3G, 4G, 5G, LTE, DVB, and Microwave Radio Fading Simulators.

The LDA-906V unit’s power and control connection is from a standard USB type-B female. Two counterbore holes are providing for efficient mounting and placement. The 1-channel digital attenuator is designed to operate reliably from -30 +70°C.

Lab Bricks use a native USB HID interface to avoid the difficulties inherent in using older serial or IEEE488 interfaces implemented over USB. As a result, Lab Brick users can 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.
