Latest Wideband USB Programmable Digital Attenuator Covers 10 to 13,000 MHz

Newburyport, MA – June 22, 2018 – Vaunix Technology Corporation, a manufacturer of programmable wireless network test devices, is pleased to announce the release of their new Digital Attenuator, LDA-133.

The LDA-133 Digital Attenuator is a bidirectional, 50 Ohm step attenuator. It provides fast attenuation changes from 10 to 13,000 MHz with a step size of 0.5 dB and 63 dB of control range with reliable and repeatable solid state digital attenuation. This product is sized to fit into a single rack unit for ATE applications such as; WiMAX, 3G, 4G, 5G, LTE, Microwave Radio and Satcom Fading Simulators.

The LDA-133 unit’s power and control connection is from a standard USB type-B female. Two counter- bore holes are provided for efficient mounting and placement. The single channel digital attenuator is designed to operate reliably from -30 to +70 C.

Lab Bricks use a native USB HID interface to avoid the difficulties inherent in using older serial or IEEE- 488 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. The Windows and Linux library APIs are designed for ease of use with Python, C#, C++, MATLAB, Java, LabVIEW and many other programming languages.
